Maggie Smith Was Diagnosed With Breast Cancer

Maggie revealed that she’d been diagnosed with cancer in 2009 in an interview with The Daily TelegraphWhile she didn’t say much about her diagnosis, she did admit that after undergoing chemotherapy, she was anxious about returning to live theater performances. “I’m not sure I could go back to theatre work, although film work is more tiring,” she said. “I’m frightened to work in theatre now. I feel very uncertain. I haven’t done it for a while.”

The late actress admitted that discovering she had cancer in her 70s “knocks you sideways.” She revealed that she was frightened upon learning. “It kind of takes the wind out of your sails, and I don’t know what the future holds, if anything. I don’t think there’s a lot of it, because of my age — there just isn’t. It’s all been. I’ve no idea what there will be,” she said.

What Is Breast Cancer?

Breast cancer is one of the most common forms of cancer among women, but it can appear in both sexes. There has been much support for breast cancer awareness, leading to tons of campaigns dedicated to early detection and treatment, per The Mayo ClinicSome symptoms include a lump in the breast, changes in appearance to the breast (including an inverted nipple), and peeling skin over the breast. Breast cancer can be inherited through genes, and other factors such as age, drinking alcohol, and more can increase the likelihood of being diagnosed with it. There are also preventative surgeries and medications for people with a high likelihood of breast cancer.
