Obesity is the leading cause of postmenopausal breast cancer
points to obesity as major responsible for the most common form of breast cancer in older women. According to the researchers, the disease is even more dangerous than cigarettes and alcohol. Led by the University of Oxford in the UK, the study looked at health records of about 6,300 postmenopausal women. Knowing that at this stage of life the high levels of the estrogen and testosterone hormones increase two to three times the risk of having breast cancer, they observed which factors influenced this growth. The results showed that obesity was more influential in the increase hormone levels than other harmful habits, such as alcohol consumption and smoking. In addition, according to researchers, pregnancy, use of contraceptives in pill and menopause also alter the female hormone levels. However, since weight is a possible trait of change, obesity should be at the top of the list.
Although the likelihood of breast cancer is also associated with family history, it is important for women to be aware of how your lifestyle can increase or decrease your risk.
Symptoms of breast cancer
In its early stages, breast cancer usually has no symptoms. As the tumor develops, you may notice the following signs:
Nodules in the breast or axilla that persist after your menstrual cycle are usually the first symptom. The lump does not hurt, although some women feel pangs. Nodules are usually visible on mammography long before they can be felt by touch;
2. Swelling in the armpit;
3. Although nodules are painless, pain and tenderness in the breast may be alert. Significant enlargement or removal of the breasts may indicate a tumor that can not be seen or felt;
4. Changes in breast size, contour, texture, or temperature; a reddish, bumpy surface, such as an orange peel, may be a sign of advanced cancer;
5. Changes in the nipple, such as the appearance of being turned inward, itching, burning, or ulceration may be symptoms of Paget's disease, a localized cancer;
6. Release of fluid through the nipple, which may be clear, with blood or other color are usually signs of benign tumors, but may be caused by cancer in some cases;
7. An area similar to marble under the skin,
8. An area that is remarkably different from any other area of the sinus.
Mouth sores can be uncomfortable, sore and look bad. They can be caused by bacterial, viral or fungal infections, a loose orthodontic cord, an improperly fitted prosthesis, or a cutting edge of a fractured tooth or restoration. Among the most common oral wounds are thrush and herpes. Canker sores are small ulcers with a white or gray base and a red edge.
Obesity is now considered a public health problem and its prevalence, across all age groups, is increasing worldwide. In Brazil, IBGE data for 2014 show that 15% of children between 5 and 9 years old and 25% of adolescents are overweight or obese. The increase in these indices is mainly related to environmental factors such as reduced time spent on physical activities and changes in dietary habits, reduced fruit and vegetable intake and increased consumption of processed foods rich in sugars and fats, with a high caloric value.
