Certain cancers may cause fatigue directly or indirectly, for example by causing anemia, inflammation, or changes in the body’s metabolism.
If extreme tiredness continues despite adequate rest, speaking with a healthcare professional may be appropriate.
3. Changes in the Skin
Changes in the skin are another sign that should be monitored.
Pay attention to changes in moles, unusual discoloration, persistent sores, or growths that do not heal normally.
For example, a mole that changes in size, shape, or color may require medical evaluation because some changes can be associated with melanoma.
Persistent skin lesions that do not heal can also have several possible causes, including certain types of skin cancer.
Yellowing of the skin or the whites of the eyes, known as jaundice, can also indicate a medical problem involving the liver, gallbladder, pancreas, or other parts of the body.
Not every skin change is cancer, but unusual or persistent changes deserve attention.
4. Persistent or Unexplained Pain
Pain is common and can have many causes.
An injury, infection, muscle problem, arthritis, or other medical condition can all cause pain.
However, pain that persists, gets worse over time, or has no clear explanation should be evaluated by a healthcare professional.
Certain cancers can cause persistent pain depending on where they develop.
