What is breast cancer?

Breast cancer is one of the most common cancers in women. It usually occurs in the breast tissue and is a type of cancer called "adenocarcinoma", which means that the cancer cells originate from the glandular tissue. There are also other types, such as sarcomas that originate from muscle, fat or connective tissue. Based on the histopathologic type of breast cancer, breast cancer is classified into two broad categories: breast cancer in situ and invasive cancer. 

The exact cause of breast cancer is not fully understood, but there are a number of possible risk factors, such as family genetics, age, hormone exposure, obesity, and dietary habits. According to the World Health Organization, in 2014, there were 5,410 new cases of breast cancer and 2,524 deaths in Malaysia, the second highest mortality rate.

So can middle and late-staged breast cancer be treated? Minimally invasive techniques with few side effects and minimal trauma allow breast cancer patients to avoid mastectomy and be free from the side effects of radiation and chemotherapy.
