Women have more glandular cells than men. If we take into account the degree of hormones exposure to these cells, it becomes clear that the risk of getting breast carcinoma in women is higher. Men, too, can get sick, but their chances are estimated about a hundred times less.
The risk of carcinoma formation may increase with age, especially after 50 years.
The greatest danger of getting carcinoma is susceptible to those patients who had cases of this disease in their genus. Moreover, the closer the affected relative (mother, sister), the greater the risk of the disease.
One of the risk factors for carcinoma is the absence of pregnancy, or infertility. Successful pregnancy and childbirth reduce this risk.
Long-term treatment with hormonal drugs, prolonged intake of oral contraceptives increases the risk of carcinoma formation.
Regular use of alcohol significantly increases the chances of developing cancer, including breast carcinoma. For this reason, women, especially after age 40, should better not drink alcohol.
The proven risk factor is obesity, since excess weight in most cases implies an increased amount of estrogens in the body, which can cause the development of a cancerous tumor.
