1.Changes in Your Skin
A new spot on your skin or one that changes size, shape, or color could be a sign of skin cancer. Another is a spot that doesn’t look the same as all the others on your body. If you have any unusual marks, have your doctor check your skin. They will do an exam and may remove a small piece (called a biopsy) to take a closer look for cancer cells.
2.Nagging Cough
If you don’t smoke, there’s very little chance a nagging cough is a sign of cancer. Usually, it’s caused by postnasal drip, asthma, acid reflux, or an infection. But if yours doesn’t go away or you cough up blood — especially if you are a smoker — see your doctor. They may test mucus from your lungs or do a chest X-ray to check for lung cancer.
