Lymphoma causes swollen lymph nodes when cancer has metastasized from other parts of the body
While winter comes with a barrage of illnesses related to cold and flu, for many people it can cause havoc with their health. Nasty winter bugs like COVID-19, RSV, norovirus, or the common cold have been surprisingly high this cold weather season across the world.
However, as hospitalisations from these viruses have been unusually higher than usual, most cases see people suffer from a familiar set of symptoms, including a blocked or runny nose, sneezing, sore throat, cough, and extreme fatigue. According to doctors, another symptom that occurs—a sign your body is fighting an infection—is swollen glands.
Swollen lymph nodes could be due to lymphoma
Doctors say swollen glands are not always caused by viral infections.
Apart from bacterial infections, tuberculosis, lupus, or even arthritis, swelling in your lymph nodes can also be due to cancer—lymphoma. According to doctors, lymphoma causes swollen lymph nodes when cancer has metastasised from other parts of the body, like breast, lung, or pancreatic cancer. So, you must get yourself checked if the following symptoms are there:
- The swelling lasts for more than two weeks
- The lymph node feels hard or fixed at a place
- It is painful
- You have accompanying symptoms like weight loss, night sweats, fever, or fatigue.
- You have a known history of cancer
What is lymphoma?
Lymphoma is a kind of blood cancer that affects the lymphatic system, which is part of the immune system. It's a broad term for cancers that begin in the lymph system.
According to doctors, lymphoma is considered a blood cancer because the condition starts in white blood cells—known as lymphocytes—in your lymphatic system. There are two main lymphoma categories known as Hodgkin lymphoma and non-Hodgkin lymphoma, along with more than 70 lymphoma subtypes. Lymphomas can be aggressive, fast-growing, or indolent, slow-growing.
Where do the swollen lymph nodes appear?
Doctors say swollen lymph nodes can appear on different parts of the body depending on the health issue. They can be formed on your upper body, on the neck, under the jaw, or behind the ears; it could be a sign of an upper respiratory infection or dental issues. And so, if they are in the armpits, they can be related to infections in the arms or breasts, or even breast cancer.
'Deep abdominal lymph nodes', such as those near the pancreas, may be more concerning because they could signal cancers, like pancreatic cancer.
What are the other symptoms of lymphoma?
Many lymphoma symptoms are like those of other less serious ailments like colds and coughs. However, apart from that, a few other changes in your body that do not go away within a few weeks include:
- Painless swelling of lymph nodes
- Persistent tiredness and exhaustion, despite getting enough rest
- Fever that doesn’t go away even after three days
- Drenching night sweats
- Shortness of breath
- Unexplained weight loss without dieting or exercise
