Pain with cancer often occurs when a tumor grows and presses on bones, nerves, or organs. Surgical procedures, chemotherapy, and radiation that are intended to treat cancer can also cause pain.

In some cases, the medical tests used to detect the presence of cancer, such as bone marrow aspiration, can cause pain.

Different types of cancer pain include:

  • Acute pain. This is bad pain that lasts a short time.
  • Chronic pain. This is mild-to-intense pain that comes and goes over a long time.
  • Breakthrough pain. This is sudden, severe pain that lasts for a short time while you are taking medicines that usually control your pain.
