LOS ANGELES   -    US actress and activist Jane Fonda announced Friday night that she has cancer, and has be­gun chemotherapy in her battle against the disease. The 84-year-old Oscar winner, a prominent supporter of the Democratic Party, vowed to fight the “very treatable” illness. “I’ve been diagnosed with non-Hodgkin’s Lymphoma and have started che­mo treatments,” she wrote on her verified Insta­gram account. “This is a very treatable cancer. 80 percent of people survive, so I feel very lucky. “I’m also lucky because I have health insurance and ac­cess to the best doctors and treatments.” Fonda, an avowed environmentalist and social campaign­er, said her position was more fortunate than that of many others in her situation. “Almost every family in America has had to deal with cancer at one time or another and far too many don’t have access to the quality health care I am receiving and this is not right,” she wrote. Non-Hodgkin’s lymphoma is a kind of cancer that starts in the lymphatic system, a part of the body’s immune de­fenses, and can develop into widespread tumors
