Angelina Jolie's mastectomy highlights need for less barriers to genetic testing

Angelina Jolie’s decision to undergo a double mastectomy is not only a courageous one, but it is also likely the right one.

In the field of breast cancer, it is clearly understood that the risk for hereditary breast and ovarian cancers can be evaluated by the presence of mutations of the BRCA1 and BRCA2 genes in the body.  The presence of either BRCA mutation equates to a more than 80 percent chance of developing breast cancer and a more than 40 percent chance for the development of ovarian cancer.

There are three treatment options for those who have been found to have the BRCA mutation. Some patients may choose to increase surveillance with mammograms and ultrasounds, while other patients may consider taking breast cancer medicines, like tamoxifen, to reduce the risk.  However, many patients are now choosing prophylactic surgery.  

The decision to do prophylactic surgery should only be made after extensive counseling, and it should take into account the patient’s ability to recover.  This kind of surgery should also be done in a hospital where multiple teams of surgeons and physicians can participate in the patient’s care, since it will require reconstructive surgery as well.  Reconstructive surgery techniques have improved greatly, but patients should still look for a surgeon who is proficient in doing breast reconstruction after a prophylactic, bilateral surgery.

A simple genetic test can identify the presence of BRCA mutations in the body, helping people to know if these interventions are necessary. The test requires a blood sample from the patient, and if either the BRCA1 or the BRCA2 mutation is detected, appropriate medical decisions can be made.  This blood test is highly recommended for patients who have demonstrated a family history of these types of cancers or whose immediate family members have developed early onset ovarian or breast cancer.

However, as Jolie wrote in her op-ed, there is a significant barrier to having the BRCA test done. The cost of the test is approximately $2,000 in the United States, and not all insurances pay for it.  To me, this is something that needs further discussion, because the future of medicine depends on genetic testing and DNA sequencing of these kinds of mutations.  By far, they are the best methods for predicting which patients might be at risk for developing these deadly diseases later in life.

Angelina Jolie reveals she had preventive double mastectomy after discovering cancer gene

Angelina Jolie says she underwent a preventive double mastectomy earlier this year because she carries a gene that increases her risk of developing breast cancer and ovarian cancer.

In a New York Times article published late Monday, Jolie says she carries the "faulty" BRCA1 gene. She writes that the risk of developing cancer varies, but doctors estimated she had an 87 percent risk of breast cancer and a 50 percent risk of ovarian cancer. 

Jolie, whose mother died at age 56 after a long battle with cancer, says she decided to have the preventive mastectomy to be "proactive" for the sake of her six children with her partner, Brad Pitt.

"Today it is possible to find out through a blood test whether you are highly susceptible to breast and ovarian cancer, and then take action," Jolie writes.

Jolie says she began the process on Feb. 2 and it took three months for her to fully recover. She says she is sharing her story to encourage other women who may not be informed about the procedure and their options.

"I wanted to write this to tell other women that the decision to have a mastectomy was not easy," she writes. "But it is one I am very happy that I made. My chances of developing breast cancer have dropped from 87 percent to under 5 percent. I can tell my children that they don’t need to fear they will lose me to breast cancer."
