Unlike fatigue, which results from lack of sleep and tiredness, fatigue that can indicate more serious conditions, such as cancer, is persistent.
Certain types of cancer that cause fatigue include leukemia and lymphoma, colon or stomach cancer (which causes slow internal bleeding and leads to anemia), or liver cancer.
Skin changes
Any change in your skin should be taken seriously.
Whether it’s moles, lumps, or skin discoloration, consult your doctor.
Possible skin changes to watch out for include: moles with irregular borders or changes in color and size (likely signs of melanoma), persistent sores that do not heal (may indicate skin cancer), yellowing of the skin and eyes (jaundice) (related to liver or pancreatic cancer), dark spots or excessive itching (may indicate cancer of internal organs).
