Breast cancer may develop in one part of the body, but it’s not just one disease. In fact, oncologists think of breast cancer as at least three different types of diseases.

Triple-negative breast cancer (TNBC) describes breast cancer cells that do not have estrogen, progesterone, or HER2 receptors. It makes up approximately 15 percent of all breast cancers and is typically more aggressive than the other two types, estrogen receptor-positive breast cancer and HER2-positive breast cancer.
“It may be the smallest group, but TNBC still represents thousands of women with breast cancer, so it is a very important group for us,” says Erica Mayer, MD, MPH, a medical oncologist at Dana-Farber’s Susan F. Smith Center for Women’s Cancers.

Although there are two main types of cervical cancer, known as adenocarcinoma and squamous cell carcinoma, they’ve generally been treated as one disease, with the same approach to treatment. In a recent study, my colleagues and I surveyed the DNA in both types of cervical cancer cells to see if there were any differences. Such variations may help explain why the two types sometimes behave the way they do, and guide us toward treatments that work best in one type or the other.
During cancer treatment, a nutritious and well-rounded diet can help you cope with side effects of chemotherapy, maintain energy and support the immune system. If you are preparing for a mastectomy or other major surgery, a healthy diet will also provide nutrients to help optimize healing time.
Most patients who undergo a mastectomy can return to regular eating habits two weeks after the surgery, but nutritionists recommend a healthy diet to be ideally implemented before the procedure to help you heal and set up long-term healthy eating habits. There are several foods we suggest make it to your plate both before and after the procedure:
