Scientists don't fully understand why a person has cancer, but it seems that the disease is influenced by genetics, the environment, eating habits, family history and even the profession. Karma. Here are 6 things that science has found or confirmed to be associated with cancer risk in 2019.
In October, the Committee for Responsible Medicine, an organization that promotes health through plant nutrition and reduced consumption of animal products, recommended the FDA add a warning label. for cheese made from cow's milk.
The petition cited research that suggested high-fat cheese products were linked to an increased risk of breast cancer by 53%.
Cheese is thought to be a risk factor because hormones used to treat commercial dairy cows have been linked with an increased risk of breast cancer. The saturated fat in cheese also plays a role in increasing cancer mortality.
But overall, research on the health effects of cheese is conflicting. A 2017 analysis of the available evidence found that cheese did not increase the risk of death from heart disease or death in any way, including cancer.
And, low-fat dairy products are actually linked to many health benefits, especially as part of a healthy eating plan like the Mediterranean diet.
"There is no danger in cheese," nutritionist Keri Gans once said. "We cannot blame anything for a specific food, as much as we want. We need to consider a person's overall diet."
Although e-cigarettes were once advertised as a safer alternative to cigarettes, it is now clear that this habit is not without risks.
According to the most recent data, there have been more than 2,050 cases of e-cigarettes and at least 39 people have died.
Experts are still trying to figure out exactly what makes e-cigarettes dangerous, but it is thought to cause inflammation in the lungs and mouth, both of which are linked to an increased risk of cancer.
Research in mice has also linked the substances in electronic cigarette vapors to a higher risk of cancer.
There is growing evidence that processed meats, including sausages, ham and bacon, are linked to an increased risk of kidney, colon and stomach cancer, partly due to Nitrates are used to preserve these foods.
According to a study published this year, red meat, even in moderate amounts, has been associated with colorectal cancer.
And, any meat that is baked at high temperatures or on an open flame has been found to cause a chemical reaction, forming carcinogens when the fat and water from meat combine with smoke and fire.
However, a controversial study in September suggested that eating red meat and processed meat may not actually increase the risk of cancer, heart disease and other chronic diseases.
Research, analyzing past evidence about meat consumption, reports that the health benefits of cutting meat are "meager" compared to the enjoyment most people get from eating meat.
However, experts still suggest removing the sausage.
"It is weird to say that because meat eaters like meat, we should not ask them to change their behavior," said Dr. Frank Hu, dean of nutrition at TH Chan School of Public Health, Harvard University, said.
On August 16, 2019, two women filed a lawsuit against breast implant manufacturer Allergan.
Previously, the FDA had received 457 reports of BIA-ALCL, including 9 "attributable" cancer deaths, according to the FDA open letter to physicians.
The company recalled a biocell called breast implant, in July after becoming more aware of cancer.
Experts say this type of cancer is not a breast cancer but rather a type of lymphoma (lymphoma), which affects white blood cells. It develops in a layer of fibrous tissue that forms around the breast lift bag.
It is not completely clear why BIA-ALCL is developing. However, the disease can, and often happens, many years after surgery. Symptoms include sudden pain and swelling that appear long after the patient has fully recovered.
Often paired with a cozy chair and perhaps a good book, 2019 research found that hot tea is one of the latest in relation to long-term cancer risk.
Specifically, drinking hot tea can nearly double the risk of esophageal cancer.
The researchers looked at data from more than 50,000 people and found that drinking two large cups of tea a day, at a temperature of 60 degrees Celsius, was associated with a 90% higher risk of esophageal cancer.
It is not clear whether it is the drink itself or the temperature, because the authors did not study other hot drinks. However, experts suspect the risk is caused by heat damage to the esophagus, which can occur with any hot food or drink.
Tea itself has lots of health benefits, especially green tea, which contains many compounds called flavonoids that are linked to better cardiovascular health and may reduce inflammation.
Fortunately, the solutions for tea and drink are simple: Allow the tea or coffee to cool before drinking.
Pesticides have long been suspected to cause cancer, and this year, new evidence has linked glyphosate, common in herbicides like Roundup, to a form of liver disease that increases the risk of liver cancer.
Earlier this year, a court ruled that Monsanto, a 'big' company in US agriculture, had to pay $ 2 billion to a couple with non-Hodgkin lymphoma, a form of lymphoma, after when using the company's herbicides for 35 years. The court found Roundup to play a "significant" role in the victim's cancer, according to the lawsuit.
However, the US Environmental Protection Agency believes that the proper use of glyphosate does not pose a risk to public health.
