The stats are more horrible in Asian countries as in Pakistan 1 in 9 women is diagnosed with this type of cancer. It’s an issue of great concern due to its increasing figures around the globe. The death rate is also increasing due to the late diagnosis of the disease and lack of awareness relating to risk factors for breast cancer.
Who is more vulnerable to Breast cancer?
Breast Cancer is not a contagious disease. It occurs due to a variety of environmental and genetic factors. Women are more susceptible to cancer, while the disease is rare in men. It occurs in less than 1% of men, so women are the most targeted victims. Those with a family history of the disease and reproductive problems are more prone than others.

Genetic mutation is the most common cause of this cancer. 5 to 10 percent of breast cancer is hereditary. BRCA1 and BRCA2 are the two genes that are responsible for the production of protein. These proteins are responsible for the repair of damaged DNA in normal cells. Mutations in these two genes lead to Breast cancer when inherited from parents to offspring.
Obesity also increases the risk of cancer. Enhanced body weight disturbs the hormonal balance of the body. Hormonal imbalance leads to several health problems such as; breast cancer and mutations in the gene. The presence of more fat increases estrogen levels which leads to breast cancers.

For those aged 40 to 50, the ratio rises to 1.5%, or 1 in 68 women. From age 60 to 70, the percentage goes up to 3.6%, which means one in 28 women is diagnosed with cancer.
