Lymphoma Symptoms Explained As Blink 182's Mark Hoppus Says He's 'Cancer Free'

Blink 182's Mark Hoppus has announced via Instagram that he is now "cancer-free" after a visit to his oncologist.

The bassist announced in June this year that he was receiving chemotherapy treatment, then going on to elaborate the following month that he had been diagnosed with diffuse large B-cell lymphoma stage IV-A, on a Twitch stream.

Hoppus added in July that the cancer had been found in four areas of his body: "I don't know how exactly they determine the four-part of it, but it's entered enough parts of my body that I'm stage IV, which I think is the highest that it goes. So, I'm stage IV-A."

B-cell lymphoma is a type of non-Hodgkin lymphoma that attacks the immune system. It grows in the white blood cells that are responsible for producing antibodies, known as B-cells, a vital part of a person's immune response.

B-cell lymphoma usually starts in the lymph nodes, hundreds of small bean-shaped structures found throughout the body, with large clusters in the neck, chest, abdomen and underarm.

This form of cancer also appears in different areas of the body that are also connected to the immune system, like bone marrow and the spleen. This means these types of cancer interfere with the immune system and if left untreated, can mean a sufferer's body can be left unable to fight infection.

B-cell lymphoma can also make its way out of this system and find its way to the brain, breast, skin, or the gastrointestinal tract.

Diffuse large B-cell lymphoma, as suffered by Hoppus, is one of the numerous types of B-cell lymphoma and is the most common form of non-Hodgkin lymphoma in the United States. It is most commonly found in people over 60, Hoppus is just 49.

This form of B-cell lymphoma usually begins as a rapidly growing lymph node in one of those main clusters. This means enlarged lymph nodes are the main symptom of diffuse large B-cell lymphoma, with other symptoms including night sweats, unusual weight loss, loss of appetite, extreme fatigue, fever and even extreme itchiness.

While it grows quickly and can be quite aggressive, the American Cancer Society says the five year survival rate for non-Hodgkin lymphoma like diffuse large B-cell lymphoma is 70 percent.

Lymphoma Action in the U.K. adds that diffuse large B-cell lymphoma responds well to treatment and many people with the cancer go into complete remission after treatment.

People with stage I or II diffuse large B-cell lymphoma are treated with chemotherapy, which is sometimes followed by radiotherapy. More advanced stages, III and IV, are treated with multiple cycles of chemo-immunotherapy.

Announcing his recovery on Instagram, Hoppus added that he will continue to get scans every six months and hopes to be back to normal by the end of the year.

"Today is an amazing day and I feel so blessed," the bassist concluded.
