Cancer is a group of diseases characterized by the uncontrollable growth and spread of abnormal cells. While many cancers progress silently, there are some signs and symptoms that should not be ignored.

In this article, we will discuss some common signs and symptoms of cancer that you should pay attention to.

1. Unexplained Weight Loss

If you have not made any changes to your diet or exercise routine but are losing weight, it may be a sign of cancer. Unexplained weight loss can occur in many types of cancer, including pancreatic, lung, colon, and stomach.

2. Fatigue

Cancer-related fatigue can be severe and persistent, even with rest. It may be a symptom of cancer or a side effect of cancer treatment. If you are experiencing fatigue that has no apparent cause, consult your doctor.

3. Persistent Pain

If you have persistent pain that does not go away, it may be a sign of cancer. For example, back pain may be a sign of ovarian, colon, or pancreatic cancer.

4. Skin Changes

Skin changes are often symptoms of skin cancer, but they can also be a sign of other types of cancer. For example, reddish or yellowish patches on the skin can be a sign of breast cancer.

5. Changes in Bowel or Bladder Habits

Changes in bowel or bladder habits that last for more than a few days can be a sign of cancer. For example, bloody or narrow stools can be a sign of colorectal cancer.

6. Persistent Indigestion or Trouble Swallowing

Difficulty swallowing or indigestion that does not go away can be a sign of esophageal cancer.

7. Persistent Cough

A persistent cough that lasts more than three weeks can be a sign of lung cancer.

8. Unusual Bleeding or Discharge

Unusual bleeding or discharge can be a symptom of different types of cancer. For example, blood in the urine can be a sign of bladder or kidney cancer.
