More than half of all cancers could be prevented

More than half of all cancers could be prevented

Smoking accounts for about a third of all cancers in the United States and up to three-quarters of lung cancer cases in the country, according to an article in the journal Science Translational Medicine . From data like these, a team led by an epidemiologist at the Cancer Center at the Washington University School of Medicine concluded that more than half of all types of cancers is preventable.

Previous studies also show that taking the vaccines against HPV and hepatitis could prevent cervical and liver cancer, respectively. Skin cancer, on the other hand, can be prevented by simply using sunscreens or not exposing oneself to the sun within 10 to 16 hours.

The results of this new analysis show that practicing exercise, having a diet balanced and non-smoking are the main habits able to avoid nearly half of the 577,000 cancer deaths in the United States. Data from the National Cancer Institute (Inca) estimate that in Brazil there will be 520,000 cases in 2012.

However, experts point out a series of obstacles that prevent most people from adopting these simple measures. One is the skepticism that cancer can be prevented and another is the custom to intervene too late to treat the problem.

Adopt ten steps to prevent various types of cancer

According to the IBGE, cancer is the second largest cause of death in Brazil - being responsible for 15.6% of deaths - only losing to cardiovascular diseases (such as heart attack and hypertension). This is mainly due to increased exposure to risk factors, such as cigarette smoking, poor diet and alcohol abuse. To stimulate the population in the struggle for control and prevention, the Institute of Cancer of the State of São Paulo (Icesp) has released a booklet listing the ten steps that remove the disease. Do not smoke

To give you an idea, 90% of lung cancer cases are responsible for cigarette smoking - the other 10% are due to secondhand smoke. Smoking is also the major culprit for 30% of the occurrence of other cancers, such as mouth, larynx, pharynx, esophagus, stomach, pancreas, liver, kidney, bladder, cervix and leukemia. Do not abuse alcohol

"Alcohol increases the chance of developing some tumors, such as the gut, esophagus and liver, but what is most noticeable is that it potentiates the effects of tobacco," says the oncologist Gilberto de Castro Jr ., of the Cancer Institute of the State of São Paulo (Icesp).

3. Use condoms

Today, it is known that human papillomavirus (HPV) - sexually transmitted disease - is primarily responsible for some cancers like cervical, vulva, penis and oropharynx (throat) cancer. That is why it is important to always use condoms - even for oral sex.

4. Safe sex also avoids hepatitis B virus (for which there is a vaccine) and hepatitis C. "These types of hepatitis can lead to cirrhosis and progress to liver cancer," he says. the oncologist Gilberto. In the case of hepatitis C, contagion usually occurs through blood contact, but it is also a risk factor for this type of cancer.

5. Have a balanced diet

Avoid excessive consumption of sugars, fats, red meat, pork and processed. Invest in a healthy diet rich in vegetables, fruits and vegetables. Although not all of these foods are directly related to cancer, they can trigger processes that can give rise to cancer cells.6. Avoid eating high-sodium foods and preservatives

Processed foods - which include canned and sausage like mortadella, ham, salami, mortadella, bacon and sausage - are rich in a substance called nitrosamine, which is carcinogenic. For this reason, nutritionist Roberto Navarro recalls, it is important that this type of food is avoided to the maximum, as well as

fast-foods

, which in general are processed.

7. Sun care

Use sunscreen daily and avoid exposure between 10am and 4pm UVA and UVB rays emitted by the sun are responsible for the cellular changes that lead to skin cancer. So protecting yourself from the sun is so important in the fight against cancer. In addition to the sunscreen - which, Gilberto de Castro Jr. warns, should have a minimum factor of 20 -, it is preferable to sunbathe just before 10 am and after 4 pm and not to give up physical barriers such as hats, umbrella, caps and sunglasses. 8. Practice physical activity every day The recommendation is that the exercise should last at least 30 minutes. The practice of physical activities promotes a general good to the body and also protects against cancer. Roberto Navarro says that this is due to the ability, especially of aerobic exercises, to decrease the circulation of pro-inflammatory cytokines in our body.

9. Stay alert to your health

Seek expert assistance should you notice any abnormality in your body We know that our body gives signals when something is not right. This also holds true for cancer cases. It is important to pay attention to the body, because only then can you notice the presence of some strange lump, an ingrowth, spot on the skin or another sign. The ICESP oncologist advises that, if something unusual happens, a doctor will be contacted.

10. Take an annual checkup

It is important to perform all early diagnostic exams indicated by your doctor. There are a number of tests that are crucial in detecting the various types of cancers. Among them, Gilberto de Castro Jr. recalls mammography, which must be done from the age of 50 to detect breast cancer or the collection of PSA - a blood test that can detect prostate cancer.


What is hidradenitis suppurativa?

What is hidradenitis suppurativa?

Sometimes also called "hidrosadenitis" or "reverse acne" by dermatologists, hidradenitis suppurativa manifests itself in several ways, which may vary from person to person. Lighter forms of suppurative hidradenitis may occur with the appearance of small nodules, blackheads, or some cysts, whereas people with more severe forms of the disease may have repeated or multiple abscesses that sometimes release pus with a odor unpleasant.

Newly discovered bacterium may have a role in gum disease

Newly discovered bacterium may have a role in gum disease

Researchers at the University of Michigan have identified a bacterium normally present in the buccal flora of mice they called NI1060. This bacterium is associated with the development of a model of periodontitis in rats. The researchers found that NI1060 accumulated at sites where gum tissue was damaged and activated a protein in the buccal cavity that stimulates bone-destroying cells.
