infection. If there is no infection, a doctor will typically order a biopsy.
4. Weight Loss Without Trying
Unexpected weight loss is a concern. Most of us don’t lose weight easily. What we’re talking about here is more than simply a few pounds from a stepped-up exercise program or eating less because of a busy schedule. If a man loses more than 10% of his body weight in a time period of 3 to 6 months, it’s time to see the doctor.
Your doctor should do a general physical exam, ask you questions about your diet and exercise, and ask about other symptoms. Based on that information, the doctor will decide what other tests are needed.
5. Persistent Cough
Coughs are expected, of course, with colds, the flu, and allergies. They are also sometimes a side effect of a medication. But a very prolonged cough — defined as lasting more than three or four weeks — or a change in a cough should not be ignored. Those cough patterns warrant a visit to the doctor. They could be a symptom of cancer, or they could indicate some other problem such as chronic bronchitis or acid reflux.
6. Difficulty Swallowing
Some men may report trouble swallowing but then ignore it. But swallowing difficulties may be a sign of a GI cancer, such as cancer of the esophagus. Let your doctor know if you are having trouble swallowing. Your doctor should take a careful history and possibly order a chest X-ray and a barium swallow. The doctor may also send you to a specialist for an upper GI endoscopy to examine your esophagus and upper GI tract.

7. Blood
Anytime you see blood coming from a body part where you’ve never seen it before, see a doctor. If you start coughing up blood, spitting up blood, have blood in the bowel or in the urine, it’s time for a doctor visit. It’s a mistake to assume blood in the stool is simply from a hemorrhoid.
Your doctor should ask you questions about your symptoms. The doctor may also order tests such as a colonoscopy. This is an examination of the colon using a long flexible tube with a camera on one end. The purpose of a colonoscopy is to identify any signs of cancer or precancer or identify any other causes of the bleeding.
8. Mouth Changes
If you smoke or chew tobacco, you need to be especially alert for any white patches inside your mouth or white spots on your tongue. Those changes may indicate leukoplakia, a pre-cancerous area that can occur with ongoing irritation. This condition can progress to oral cancer.
You should report the changes to your doctor or dentist. The dentist or doctor should take a careful history, examine the changes, and then decide what other tests might be needed.
9. Indigestion
Many men, especially as they get older, think “heart attack” when they get bad indigestion. But persistent indigestion may point to cancer of the esophagus, throat, or stomach. Persistent or worsening indigestion should be reported to your doctor.
Your doctor should take a careful history and ask questions about the indigestion episodes. Based on the history and your answers to the questions, the doctor will decide what tests are needed.
