8. Swollen Lymph Nodes
Sometimes swollen lymph nodes can be the first sign of cancer. This is often the case with lymphoma, a type of blood cancer that develops in the lymph nodes. Other times, lymph nodes can swell if cancer from another part of the body has spread to nearby lymph nodes.
Cancer-related lymph node swelling typically presents as firm, painless masses that persist and grow over time, unlike infection-related swelling that fluctuates and resolves. See a healthcare professional if your swollen lymph nodes have no known reason, continue to get bigger or have been swollen for 2 to 4 weeks, feel hard or rubbery and don’t move when pushed, or come with fever, night sweats, or weight loss.
