As soon as breast cancer is detected, the more likely it is to complete his treatment of the treatments that are available today. If you ascertain, through touch, a breast mass should contact your doctor immediately to make breast examination. A mass in the breast can be malignant (cancerous) or benign (non-cancerous). Not all masses are cancerous. More than 90% of them are not cancerous. In duration or breast pain before menstrual cycle is common for many women and is not a sign of breast cancer. Measures which are benign breast may be solitary (single) and multiple (multiple). Their development is often linked to hormonal effects in normal breast tissue and there is no way to prevent their development.
WHAT CAUSES BREAST CANCER and WHO TOUCH HE?
Below we list some of the known risk factors for breast cancer now. What should be emphasized is that having one or several risk factors does not mean that these factors will develop breast cancer but which may contribute to its development. Risk of developing breast cancer is not related to breast size. Breast cancer is the most common cancer in women.
Although rare, breast cancer can also affect men.
The main differences between breast cancer in men and women are:
→Breast cancer in men is often diagnosed later in advanced stages (metastatic) maybe this is related to the denial of the importance of a body of men in their bosom.
→ Men affected by breast cancer are more likely to have inherited genetic mutations that increase the risk of developing breast cancer.
››Being female ›› Risk of developing breast cancer increases with age. The risk doubled in age between 45-46 years.››Diagnosis of breast cancer in a woman increases the risk of having another breast cancer.›› Family history of breast cancer, in particular the diagnosis of breast cancer in mother, sister, aunt, the child of a woman increases the risk of breast cancer in this woman.
OTHER FACTORS OF RISK
→Defects or mutations in several genes that can be inherited from parent to child can increase the risk for breast cancer. Women and men who have BRCA1 and BRCA2 mutations have a great risk of having breast cancer during their lifetime. However, it is seen that only 5% of women with breast cancer have mutations in these genes.
→Women with a family history of cancer of the cervix, uterus, and rectum have a risk relatively high.
→Duration of exposure to estrogen in women is a risk factor for breast cancer. The level of estrogen in a woman increases when she enters puberty (which coincides with the arrival of menstruation) and lowered after entering menopause and pregnancy.
Therefore increasing exposure to estrogen are:
- Women which had menstruating before age 12 years.
- Women who go through menopause late (after age 52 years)
- Women who are pregnant for the first time 30 years and after the age or women who have not had any pregnancy.
- A woman’s in menopauses that receive hormonal therapy, replacement (estrogen) for a period of 5-10 years.
- Hormone replacement therapy is known because facilitates the symptoms of menopause and prevent osteoporosis, therefore recommended that women go through menopause.
- Recent studies have shown that taking hormone replacement therapy for more than 5 (5-10 years) increases the risk of breast cancer by 25%. The same study showed no benefit in protecting these women against cardiovascular disease as previously thought.
- HRT considering these studies, it is recommended only for women with very worrying symptoms of menopause for a period of 2-4 years. Women who receive this therapy should be made aware of the potential increase in risk of breast cancer in order to do regular breast checks.
- Women previously diagnosed with breast cancer should not take HRT because there is a possibility that this therapy cause disease relapse.
→Alcohol is associated with the risk for breast cancer growth. →Obesity (body mass index over 25) or obesity (body mass index more than 30) increased risk of breast cancer in women after menopause. This is related to the fact that fat cells can produce estrogen, so being overweight after menopause increases the level of estrogen in the body of these women. Also measures excess fat can hide the tumor and delay its diagnosis, reducing the chances of recovery.
