The 59-year-old actor shared the news in an Instagram post, writing: "Yep. I have breast cancer. And yep, it’s super rare. Only 1% of breast cancers are men."

Mane said he initially wanted to keep his diagnosis private but decided to speak publicly about it to raise awareness of the disease among men.

"But then I found out that men are more likely to be diagnosed in advanced stages because it’s not talked about and not looked for. In fact, my doctors all dismissed it, and it was only because my wife pushed me to get the lump removed that I got in early," he wrote.

Encouraging others to be aware of the condition, Mane added: "So let’s start talking about it! 1 in 755 men will be diagnosed with breast cancer in their lifetime and if caught early, it’s VERY treatable. Time to answer the Wake Up Call! Like, Save, Share, Comment — let’s spread the word!"

According to the Mayo Clinic, male breast cancer is a rare form of cancer that develops in the breast tissue of men. Although uncommon, the disease can occur at any age, with most cases diagnosed in older men.

Treatment for male breast cancer typically involves surgery to remove the affected breast tissue. Depending on the stage and nature of the cancer, additional treatments such as chemotherapy, radiation therapy, hormone therapy, or targeted therapy may also be recommended.

Common signs and symptoms of male breast cancer include:

A painless lump or thickening in the chest area.

Changes in the skin covering the breast, including dimpling, puckering, scaling, or discoloration.

Changes to the nipple, such as scaling, redness, or an inward-turning nipple.

Discharge or bleeding from the nipple.
