Plasma cell cancers are a group of diseases that begin in a type of white blood cell called a plasma cell. These cells are part of your immune system and are normally found in your bone marrow. Their job is to make antibodies that help your body fight infections. When plasma cells become cancerous, they grow out of control and produce abnormal proteins instead of helpful antibodies. This can cause serious health problems by damaging bones, kidneys, and other parts of the body.
Plasma cell cancers are rare, but they can be serious. The most well-known type is multiple myeloma, but there are other forms too. Learning more about what causes them, how they affect the body, and what treatments are available can help people better understand this condition and what to expect.
What Causes Plasma Cell Cancers And What Types Exist
Scientists don’t know the exact cause of plasma cell cancers, but they believe it starts when the DNA in plasma cells gets damaged. This damage causes the cells to multiply when they shouldn’t and to live longer than normal. Over time, these abnormal cells build up in the bone marrow and crowd out healthy blood cells. They also create large amounts of abnormal proteins that can collect in the blood and organs, leading to further complications.
Several risk factors may increase your chances of developing plasma cell cancers. These include being older, having a family history of the disease, being male, and being African American. Exposure to certain chemicals or radiation may also play a role, although the exact connection is still being studied.
There are a few main types of plasma cell cancers:
-
Multiple Myeloma: This is the most common type. It affects many areas of the bone marrow and can cause bone pain, kidney problems, and a weakened immune system.
-
Plasmacytoma: This is when a single tumor made of cancerous plasma cells grows in one area, often in the bone or soft tissue. It may develop into multiple myeloma over time.
-
Light Chain Amyloidosis (AL Amyloidosis): In this condition, plasma cells produce abnormal proteins called light chains, which build up in organs like the heart, kidneys, or liver and affect their function.
Each type has its own symptoms and treatment plan, but they all begin with abnormal plasma cell activity.
Common Symptoms To Watch For
Symptoms of plasma cell cancers can be hard to notice at first. Many people don’t feel sick in the early stages. As the disease progresses, symptoms often develop slowly and may seem like other common health issues.
Some of the most common symptoms include:
-
Ongoing bone pain, especially in the back, ribs, or hips
-
Feeling tired or weak, often due to anemia
-
Frequent infections or trouble recovering from illnesses
-
Unexplained weight loss
-
Numbness or tingling in the arms or legs
-
Nausea, constipation, or confusion from high calcium levels
-
Kidney problems, sometimes leading to kidney failure
-
Swelling in the legs or around the eyes if the kidneys are affected
People with AL amyloidosis may also experience heart problems, shortness of breath, or an enlarged tongue. Because these symptoms can be caused by many other conditions, it’s important to see a doctor if they don’t go away or if they get worse over time.
How Doctors Make A Diagnosis
Diagnosing a plasma cell cancer usually starts with a visit to the doctor and a discussion about symptoms and medical history. If the doctor suspects a problem, several tests may be done to confirm the diagnosis and find out which type of plasma cell cancer is present.
A blood test can check for abnormal proteins, low red blood cell counts, or high calcium levels. A urine test might also be used to look for proteins that are being released by the cancerous cells. A bone marrow biopsy is one of the most important tests. It involves taking a small sample of bone marrow, usually from the hip, and looking at it under a microscope to see how many plasma cells are present and whether they look abnormal.
Imaging tests like X-rays, MRIs, or CT scans can help check for bone damage, tumors, or signs that the cancer has spread. In the case of amyloidosis, a tissue biopsy from an organ like the kidney or heart may be needed to see if abnormal proteins have built up there.
Once all the results are in, the doctor can determine what type of plasma cell cancer is present, how advanced it is, and which treatment options might work best.
Treating Plasma Cell Cancers
There are several treatments available for plasma cell cancers, and the best choice depends on the type of cancer, how advanced it is, and the patient’s overall health. Some people may need immediate treatment, while others can wait and be monitored closely.
Treatment options may include:
-
Chemotherapy: This uses strong drugs to kill cancer cells or stop them from growing. It can be given as pills or through an IV.
-
Targeted Therapy: These medicines attack specific parts of the cancer cells, making them less harmful to healthy cells.
-
Immunotherapy: This helps the immune system recognize and destroy cancer cells more effectively.
-
Steroids: Often used along with other treatments to reduce inflammation and help other drugs work better.
-
Stem Cell Transplant: In some cases, high-dose chemotherapy is followed by a stem cell transplant to help the body make healthy blood cells again.
-
Radiation Therapy: This can be used to shrink tumors or relieve bone pain.
For people with AL amyloidosis, treatment focuses on reducing the number of abnormal plasma cells and stopping the production of harmful proteins. Managing symptoms and protecting affected organs is also an important part of care.
Treatment can be long-term and may involve different types of therapy used together. Regular checkups, blood tests, and scans are needed to track how well the treatment is working and to make changes if necessary.
Living With Plasma Cell Cancer
Getting diagnosed with a plasma cell cancer can be scary, but many people are able to manage the disease and live fulfilling lives. Treatment is improving every year, and doctors are finding better ways to help patients feel better and stay active.
It’s important to eat well, stay physically active if possible, and keep up with all medical appointments. Some people may experience side effects from treatment, like fatigue or nausea, but there are ways to manage these with the help of the care team.
Mental and emotional health is also important. Talking to a counselor, joining a support group, or simply connecting with family and friends can help reduce stress and make it easier to cope.
While there may not be a cure in every case, many people can live with plasma cell cancers for many years. Early detection, the right treatment plan, and ongoing support can make a big difference in the journey.
