Why is cancer called cancer? To find the answer, we need to go back to Greco-Roman times

Published

on

One of the earliest descriptions of an individual with cancer comes from the 4th century BC. Satyrus, tyrant of the Black Sea city of Heracleia, developed a cancer between the groin and scrotum. As the cancer spread, Satyrus felt an increasing number of pain. He couldn’t sleep, he had convulsions.

Advanced cancers on this a part of the body were considered inoperable and there have been no drugs strong enough to relieve the pain. Therefore, the doctors couldn’t do anything. Ultimately, cancer took Satyrus’ life at the age of 65.

Cancer was already well-known during this era. The text was written at the end of the fifth or the starting of the 4th century BC, the so-called Women’s Diseasesdescribed the development of breast cancer:

hard growths form (…) hidden tumors develop from them (…) pain radiates from the patients’ breasts to the throat and around the shoulder blades (…) such patients shed extra pounds throughout the body (…) respiratory becomes weaker, the sense of smell is lost (… )

Other medical work This period describes various forms of cancer. A girl from the Greek city of Abdera died of chest cancer; A person with throat cancer survived after a health care provider burned the tumor.

Where does the word “cancer” come from?

Why does the word “cancer” have its roots in the ancient Greek and Latin words for crab? The doctor Galen gives one explanation.

The word cancer comes from the same era. At the turn of the fifth and 4th centuries BC, doctors used the word – Ancient Greek word for crab – to describe malignant tumors. Later, when Latin-speaking physicians described the same disease, they used the Latin word for crab: . So the name stuck.

Already in ancient times, people wondered why doctors named this disease after an animal. One explanation was that the crab is an aggressive animal, like the crayfish aggressive disease; one other explanation was that a crab could grab one a part of an individual’s body with its claws and be difficult to remove, just as a cancer could possibly be difficult to remove once it develops. Others believed it was due to the appearance of a tumor.

The physician Galen (129-216 AD) described breast cancer in his work A technique of medication for Glauconand compared the type of a tumor with that of a crab:

We often saw a lump in the breast exactly like a crab’s. Just as this animal has feet on each side of its body, so on this disease the veins of unnatural swelling extend on each side, making a crab-like shape.

Not everyone agreed on what caused the cancer

During the Greco-Roman period, there have been different opinions about the causes of cancer.

According to a widely held ancient medical theory, there are 4 humors in the body: blood, yellow bile, phlegm and black bile. Otherwise, these 4 humors have to be kept in balance the person gets sick. It was believed that if an individual suffered from excess black bile, it might eventually lead to cancer.

The physician Erasistratus, who lived around 315–240 BC, disagreed. However, so far as we know, he has not offered another explanation.

How was cancer treated?

Cancer was treated in various ways alternative ways. It was believed that cancer in its early stages could possibly be cured with drugs.

Galena taken over that through the use of these kinds of drugs and repeatedly purging his patients with vomiting or enemas, he sometimes managed to make emerging tumors disappear. He said the same treatment sometimes prevents more advanced cancers from developing further. However, he also said that surgery is crucial if these drugs don’t work.

Surgery was often avoided because patients often died from blood loss. The most successful surgeries were for tumors at the end of the breast. Leonidas, a physician who lived at the turn of the 2nd and third centuries AD described his method, which involved cauterization (burning):

I often operate in cases where the tumors don’t reach the chest (…) After positioning the patient on her back, I incise the healthy breast area above the tumor after which cauterize the incision until a scab forms and the bleeding stops. standing. I then incise again, marking the area, cutting deep into the breast and cauterize again. I do that (cutting and cauterizing) very often (…) Thanks to this, the bleeding is not dangerous. Once I’ve finished cutting out, I cauterize the entire area again until it dries.

Cancer was widely considered an incurable disease and subsequently feared. Some individuals with cancer, comparable to the poet Silius Italicus (26-102 AD), died by suicide to end the torment.

Patients also prayed to the gods for hope for cure. An example of this is Innocentia, an aristocrat who lived in Carthage (in modern-day Tunisia) in the fifth century AD. She told her doctor that divine intervention cured her of breast cancer, nevertheless it was due to her doctor I didn’t imagine her.

From the past to the future

We began with Satyrus, a tyrant who lived in the 4th century BC. In the roughly 2,400 years since then, much has modified in our knowledge of the causes, prevention, and treatment of cancer. We also know that there are more 200 differing kinds cancer. Some people have cancer that is treated so successfully that they live an extended time.

However, there is still no general “cure for cancer” for a disease that affects approx one in five people develop throughout their lives. Only in 2022Worldwide, there have been roughly 20 million recent cases of cancer and 9.7 million cancer deaths. We clearly have a good distance to go.

Ant stings can be painful. Here’s how to avoid getting stung this summer (and what to do if it happens)

Published

on

By

The starting of summer is just a couple of days away, and plenty of of us will be looking forward to long, sunny days spent on the beach, by the pool, camping or having a picnic within the park.

Insects love summer too. Most of them right then grow and feed. However, this shared appreciation of the season can sometimes lead to conflict.

Insects have long been preyed upon by many species, including birds, mammals, amphibians, and other insects. Accordingly, quite a lot of defense mechanisms have evolved – perhaps none more familiar to humans than the sting.

Many ants have a stinger on their rear end which they use to deliver venom. It will not be the sting itself that causes pain, but relatively venom. Ant venom accommodates a mix of various chemicals, a few of which have evolved specifically to manipulate the nerve endings in our skin to cause pain.

Let’s take a have a look at the several ant stings chances are you’ll experience this summer in Australia and how to respond.

Bull ants

Bull ants (also often called bulldog ants, jumper ants, or jumper ants) are large for an ant. Some species can grow to length 4 centimeters. They are easily identified by their large eyes, long mandibles (jaws), and aggressive nature.

Their sting is immediate, hot, sharp and unambiguous, similar to that of a honey bee. The intense pain will only last a couple of minutes before being replaced by redness and swelling across the sting site.

There are many differing kinds of bull ants in Australia.

Green-headed ants

Green-headed ants are also called green ants (but not to be confused with green ants). green tree ants northern Australia, which do not sting). Green-headed ants are common and love our lawns.

About Length 6 millimetersthey’re much smaller than bull ants. They can be recognized by their shiny green-purple exoskeleton.

Green-headed ants are frequently less aggressive than bull ants, but they can still deliver a big sting. The pain from a green ant sting can construct up step by step and cause intense, sticky pain.

Fire ants

Fire ants (or imported red fire ants) are native to South America. They were detected first in Brisbane in 2001it probably moved in containers and has since spread across south-east Queensland.

Fire ants are reddish brown and black and range in size from Length 2–6 millimeters.

You will almost certainly encounter fire ants of their nests, which appear like a pile of loose dirt. A hearth ant nest has no obvious entrance, which is way to distinguish it from other similar ant nests.

Disturbing a hearth ant nest will awaken an offended mass of a whole bunch of ants and expose you to being stung.

The initial pain from a single sting seems like an intense, hot itch, although it can be controlled. However, fire ant stings rarely occur in the only digits. One ant can sting multiple times, and plenty of ants can sting one person, which can lead to a whole bunch of stings. A hearth ant sting can cause pus-filled ulcers and scarring in the next days.

If you reside in an area where fire ants are present, it’s price taking a couple of minutes to learn how to do this recognize and report their.

Electric ants

Electric ants is one other nasty random import, coming from Central and South America. Currently limited to Cairns and surroundingsthese are tiny (1.5 millimeters long) yellow ants.

Like fire ants, these ants are frequently defensive, so lots of them will sting without delay. Their sting is more painful than you’ll expect from such a tiny creature. I compare it to being showered with red, hot sparks.

If you think that you see electric ants, please report it Biosecurity in Queensland.

Australian ants should not the worst

You may be surprised to hear that Australian ants don’t even make it to the rostrum when it comes to essentially the most painful ant stings. The winners include: harvester ants (North and South America), which cause severe, sticky pain, comparable to a drill slowly rotating in a muscle – for up to 12 hours.

The gold medal goes to the sting of the South and Central American bullet ant, which has been described How:

Pure, intense, sensible pain. It’s like walking on burning charcoal with a 3-inch nail stuck in your heel.

How to avoid getting stung (and what to do if you do)

Fortunately, the answer is frequently quite simple. Look around before you sit on the bottom or unfolded a picnic blanket, avoiding places where you see ant nests or a lot of foraging ants.

The selection of footwear might also be necessary. In my experience, most stings occur on the feet of those wearing thongs.

If you get stung, generally the situation will improve by itself. The pain often subsides after a couple of minutes (sometimes slightly longer within the case of a green ant sting). The redness, swelling and itching that sometimes follows may last for several days.

In the meantime, if mandatory, ice pack it will help with the pain. If it’s particularly bad, a topical numbing cream containing lidocaine may provide temporary relief. You can get it over-the-counter at a pharmacy.

A small proportion of individuals may experience an allergic response to ant stings. In very severe cases this may include respiratory problems or ingestion. If you or a loved one experiences these symptoms after an ant sting, you need to seek urgent medical attention.

Health matters: WNBA star Napheesa Collier on her commitment to women’s reproductive health

Published

on

By

Minnesota lynx

Napheesa Collier will not be only a WNBA superstar for the Minnesota Lynx and a two-time Olympic gold medalist, but additionally the mother of her daughter Mila and an advocate for women’s reproductive health rights.

It recently decided to partner with Opill®, the primary and only every day contraceptive pill available over-the-counter within the United States. This breakthrough represents a major step forward in women’s health care by providing a convenient and accessible contraceptive option. With Opill, women not need to visit health care facilities for prescriptions, making it easier than ever to take control of their reproductive health.

The collaboration relies on Opill®’s long-standing partnership with the Women’s National Basketball Association (WNBA). “One of the reasons Opill® partnered with the WNBA is the great passion of players who use their platform to support causes they believe in,” said Leila Bahbah, leading women’s health brand at Perrigo within the US. “Napheesa exudes this passion, and together we plan to educate and empower people to take control of their reproductive health.”

Collier advocates for girls and says she is willing to have conversations, even in the event that they are difficult. “I just truly believe in everything they do at Opill®. I believe it’s important to talk to people who may become pregnant and to women about the reproductive health and contraceptive options available to them,” Collier tells ESSENCE.

He continues: “I want people to know that if they want contraception, Opill® is a great option. It is the first over-the-counter drug approved by the FDA. It is inexpensive, available. You don’t need a prescription to get it. I think that’s a key thing in today’s climate.”

Collier notes that within the off-season, he tries to travel to various colleges to talk to students about their reproductive freedoms. “Talking about this topic is essential to remove the stigma as it should not be considered a shameful topic or something that should not be discussed openly. My mother was a nurse, so it was casual to talk about it in our house, and I want to pass it on to other people too, so I’m very excited about it,” she says.

In the present political climate, many ladies with daughters are concerned about their future and reproductive health. Collier, included. “Especially because I am the mother of a young girl, it is very important to me to be able to raise her in an atmosphere where she knows her reproductive rights and health, that she has access to affordable health care and contraception if she wants it and that she can ask me these questions and have open conversations.”

Collier continues: “It’s back to education. Again, I think it’s harmful that we can’t have open conversations about birth control and other issues that are usually taboo. I think it’s harmful. I think this does a lot of harm to women. It hurts. This is harmful to our society. Being able to talk about these issues and empowering women to learn about their rights and bodies creates a safer and healthier society.”

Yes, despite what you’ve heard on TikTok, you still need to use sunscreen

Published

on

By

Summer is nearly here. But as an alternative of using sunscreen, some TikTokers just do that encouraging followers throw it away and forgo sunscreen.

They argue that it’s healthier to forgo sunscreen to get the complete advantages of the sun.

Here’s what the science really says.

How does sunscreen work?

Due to the acute UV environment in Australia, most individuals with pale to olive skin or other risk aspects for skin cancer must accomplish that protect yourself. Applying sunscreen is a key approach to protecting areas that aren’t easily covered by clothing.

Sunscreens work by absorbing or scattering UV rays before they reach the skin and damage DNA or supporting structures corresponding to collagen.

In this photo I (Katie) apply sunscreen only to the appropriate side of my face. Sunscreens absorb and scatter UV light (right side), although it can’t be seen with the naked eye (left side). The photo on the appropriate also shows where sun spots (dark spots) accumulate on my skin and where I do not care to apply sunscreen evenly – under the attention, on the cheek and completely missing the ear.

When UV molecules hit DNA, the surplus energy can damage our DNA. This damage might be repaired, but when the cell divides before the error is repaired, it causes a mutation that may lead to skin cancer.

The energy of the UV particle (photon) causes the DNA strands to break and reconnect incorrectly. This causes a tumor within the DNA strand, which makes accurate copying difficult and might introduce mutations.

The most typical skin cancers are basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). Melanoma is less common but most definitely spreads throughout the body; this process known as metastasis.

Two against three At least the Australians will one skin cancer during their lives they usually reconcile 80% all cancers in Australia.

About 99% of skin cancers in Australia are attributable to overexposure to UV radiation.

Excessive exposure to UV radiation also affects the looks of the skin. UVA rays are able to penetrate deep into the skin, where they break down supporting structures corresponding to elastin and collagen.

This causes signs premature agingcorresponding to deep wrinkles, brown or white spots and broken capillaries.

Sunscreen may also help prevent skin cancer

Consistently used sunscreen reduces the danger of skin cancer and slows skin aging.

In Queensland studyparticipants either used sunscreen day by day for nearly five years or continued their usual use.

After five years, the danger of squamous cell cancer was reduced within the day by day group 40% compared to the second group.

Ten years later, the danger of developing invasive melanoma was reduced within the group of individuals taking the drug day by day 73%

Do sunscreens block the health-promoting properties of sunlight?

The answer is a little more complicated and involves a personalised risk-benefit trade-off.

First, the excellent news: spending time within the sun has many health advantages don’t rely under the influence of UV radiation and aren’t affected by the use of sunscreens.

Sunscreens only filter UV rays, not visible light or infrared light (which we feel as heat). Importantly, a number of the advantages of sunlight are obtained through Eyes.

Visible light improves mood and regulates and possibly reduces circadian rhythm (which influences the sleep-wake cycle). myopia (myopia) in children.

Infrared light is being researched as a treatment for several conditions skin, neurological, psychiatric AND autoimmune disorders.

So what is the good thing about exposing your skin to UV radiation?

Sun exposure produces vitamin D, which is crucial for healthy bones and muscles.

Vitamin D deficiency is surprisingly common amongst Australians, peaking in Victoria at 49% in winter and lowest in Queensland at 6% in summer.

Fortunately, individuals who deal with sun protection can avoid vitamin D deficiency taking a complement.

Skin exposure to UV radiation could have advantages independent of vitamin D production, but these haven’t been proven. It may reduce the danger of autoimmune diseases corresponding to multiple sclerosis or cause the discharge of a chemical that may lower blood pressure. However, there aren’t enough details about these advantages to say whether sunscreen can be an issue.

What does this mean for you?

Exposure of the skin to UV radiation may provide some advantages that could be blunted by sunscreens. This determines whether it’s value giving up these advantages to avoid skin cancer how susceptible you have skin cancer.

If you have pale skin or other aspects that increase your risk of skin cancer, try to use sunscreen day by day on all days when the forecast UV index reaches 3.

If you have darker skin that rarely or never burns, you might want to skip using sunscreen on daily basis – although you’ll still need protection when you’re outdoors for prolonged periods of time.

For now, the balance of evidence suggests that it is healthier for people susceptible to skin cancer to proceed using sunscreen, supplementing with vitamin D as needed.
