Cancer is the second most common cause of death. It's more curable when detected earlier. Although some cancers develop completely without symptoms, some do have signs you are likely to ignore.
1. Unexplained Weight Loss
Weight loss for no known reason, not through changes in diet or exercise is a common sign of cancers related to lung, stomach or pancreas.
Fever may be a sign of early cancer in the blood such as leukemia or lymphoma. Fever may also reveal colon and kidney cancer at an early stage.
Extreme fatigue that cannot get better with rest can be a symptom of several cancer types such as colon cancer, stomach cancer or leukemia.
Sometimes bone cancer or testicular cancer can cause pain. A headache that doesn't get better after a long-time treatment may be a symptom of a brain tumor. Back pain may be a sign of cancer in ovary or colon.
5. Skin Changes
Any freckle, mole or wart that changes color, shape, or size should be examined for skin cancer. Besides, darker looking skin, reddened skin, itching, yellowish eyes and skin may also be linked to cancers.
6. Change in Bowel or Bladder Habits
Long-term diarrhea, constipation or a change in the size of the stool can be a symptom of rectal or colon cancer. Pain when passing or blood in urine can be related to bladder or prostate cancer.
