An Overview of Breast Cancer Causes

Though exact breast cancer causes continue to be fuzzy, but key risk factors are clear. Yet astonishingly, several females thought to be at high risk of developing breast cancer do not develop the disease whereas several other women that have no identified risk factors get the disease. Amongst the most important risk factors are progressing age and family case history of the disease. Risk would augment to some extent in case of women that had developed a non-malignant lump in their ovaries or breast tissues.

A woman having a direct family history or first degree blood relatives like sibling, offspring or mother that has the disease could raise her chances of developing breast cancer by two to three folds. Investigators have been able to detect duo genes that are accountable for a number of cases of breast cancer running in families – known as the BRCA1 and BRCA2. Nearly 1 female in two hundred is believed to be a carrier of these genes. Women who have the gene are predisposed to developing the disease; however, it does not ascertain that she would get breast cancer. Females having a heritable variation in either of these duo genes possess an eighty percent chance of getting breast cancer during their lifespan.

Breast cancer causesBy and large, females past the age of fifty have greater likelihood of getting breast cancer as compared to women in the younger age bracket. Furthermore, Females belonging to Afro- American race have greater likelihood of developing breast cancer prior to menopause as compared to Caucasian race women.

An association in-between hormones and breast cancer is eventually becoming comprehensible. Investigators deem that more a woman is exposed to the estrogen hormone; greater is her susceptibility of getting breast cancer. Estrogen notifies the cells to start division and greater the cell division, greater is the likelihood of some form of abnormality developing in them and perhaps turning malignant.

All through the varied phases of a woman’s life, she is exposed to rising and plummeting levels of progesterone and estrogen which is affected by the age when her menstruation commences and halts; the average span of her menstrual periods cycles and the age when she delivered her foremost child. Risk of developing breast cancer increases in case a woman has her periods prior to twelve years of age, has delivered her first baby subsequent to thirty years of age, menstruation has stopped after fifty-five years of age or she has a menstrual periods cycle lesser or lengthier than the usually occurring 26 to 29 days.

A number of studies have indicated that the use of HRT (Hormone replacement therapy) after becoming menopausal could raise chances of developing breast cancer, particularly in case it has be used for over five years.

Heavy exposure to dosages of radiation therapy could be one of the breast cancer causes. However, less dosage mammograms carry hardly any risk.

The association between diet and breast cancer has been contemplated and being obese is a significant risk factor. Those women who consume alcohol on a regular basis (crossing a daily consumption of a couple of drinks) may possibly be promoting breast cancer.

Several studies have suggested that a high-fat dietetic intake could be one of the breast cancer causes and it increases the likelihood of getting the disease. Investigators have suspected that in case a woman reduces her everyday fat intake to below twenty to thirty percent then her diet could aid in protecting her for getting the disease.
