Male Breast Cancer: The 1st Sign Matthew Knowles Saw Before His Own Diagnosis

October is breast cancer awareness month, and it's an important time for people who suffered or are currently suffering from breast cancer to speak out and raise awareness about the risk factors. People typically assume that only women suffer from breast cancer, but did you know that men can have breast cancer, too? Mathew Knowles, Beyonce's dad, is part of the less-than-1% of men who get diagnosed with breast cancer.

The First Sign Matthew Knowles' Saw

Knowles appeared on The Dr. Oz Show in 2019 about his experience dealing with breast cancer that year. He first became suspicious of breast cancer was when he noticed a drop of red blood on his white t-shirt one day, and his wife mentioned she had seen small drops of blood on the sheets for weeks. He immediately went to get a mammogram, and the news about his diagnosis was broken to him within a matter of days.


It turned out that Knowles' breast cancer was hereditary, and he had the BRCA2 gene mutation. Thankfully he was diagnosed at stage 1A and had a mastectomy as a result of the diagnosis.

Knowles wants men who are suffering from breast cancer to know that they are not alone in their fight. "I feel like there aren't any guidelines for men about this – we are left in the dark," he said.

Why Men Should Get Screened for Breast Cancer

Knowles' doctor, Dr. Susan Domchek, joined him on the show to help educate men about getting screened for breast cancer. Just like women, men have breast tissue that can have mutations, and those mutations can cause cancerous lumps (or tumors).

Men are not typically advised to do mammograms for breast cancer screening. But Dr. Domchek recommended that men get screened just to be safe. Although the disease isn't very common in men, it's not impossible for a man to have the gene mutation, as Knowles has, or other cancer-causing gene mutations that place men in a high-risk category for breast cancer, according to Domchek. If a parent has this gene mutation, that means their children also have a 50% chance of inheriting a cancer-causing gene mutation, so it's better to be safe than sorry — not only for your health but for the health of your kids' as well.

Signs to Look for in Men

Knowles noticed blood discharge from his nipples. Here are other early signs of breast cancer in men:

  • A painless lump or thickening in your breast tissue.
  • Changes to the skin covering your breasts, such as dimpling, puckering, redness or scaling.
  • Changes to your nipple, such as redness or scaling, or a nipple that begins to turn inward.
  • Discharge from your nipple.

Talk to your doctor about your risk of developing breast cancer and if you notice any of the above symptoms

Here's Dr. Oz's Mom's Regimen for Fighting Her Alzheimer's

When Dr. Oz found out in September 2019 that his mom, Suna, then 81, was diagnosed with Alzheimer's disease, he was gutted. He wondered how he missed the signs and what he could do next. Like so many caregivers, he had to recognize that his mom was not going to get better. But he also knew that he wasn't alone: There is an Alzheimer's diagnosis every 65 seconds.

Dr. Oz immediately contacted his friends and colleagues and crafted a treatment plan with two of the country's top experts in the field: Richard S. Isaacson, MD, a neurologist at NewYork-Presbyterian/Weill Cornell Medical Center and the founder of the Alzheimer's Prevention Clinic, and Dr. Rudy Tanzi, a professor of neurology at Harvard and the founder of the "Alzheimer's Genome Project," who co-discovered the first Alzheimer's gene.
