What is non-Hodgkin's lymphoma?

According to the Mayo Clinic, non-Hodgkin's lymphoma is a type of cancer that begins in the lymphatic system where "white blood cells called lymphocytes grow abnormally and can form growths (tumors) throughout the body." Signs and symptoms can include swollen lymph nodes, abdominal pain and chest pain.

"Advances in diagnosis and treatment of non-Hodgkin's lymphoma have helped improve the prognosis for people with this disease," the clinic notes.

The five-year relative survival rate for patients diagnosed with non-Hodgkin lymphoma is 73%, according to the American Cancer Society. There are more than 70 kinds of non-Hodgkin's lymphoma, and this kind of cancer is "relatively common," according to the Cleveland Clinic.

In 2022, actress Jane Fonda shared that she was battling Non-Hodgkin lymphoma. She later said she was in remission and was told she could discontinue chemotherapy. "I am feeling so blessed, so fortunate," she said on Instagram. "I thank all of you who prayed and sent good thoughts my way. I am confident that it played a role in the good news."
