Cancer doesn't present symptoms or signs that exclusively point to the disease. Many complaints can be attributed to benign conditions. However, if you experience symptoms, it's advisable to consult a doctor for further evaluation. Some common symptoms include:

Persistent Cough or Blood-Tinged Saliva

These symptoms often result from common infections like bronchitis or sinusitis.

Yet, they could also indicate cancers of the lung, head, or neck. Anyone with a persistent cough lasting over a month or with blood in their coughed-up mucus should seek medical attention.

A Change in Bowel Habits

Doctors may observe thin stools in cases of colon cancer.

Sometimes, cancer can lead to chronic diarrhea.

People with cancer might feel the constant need for a bowel movement even after having one. If any unusual bowel changes persist beyond a few days, it's crucial to seek evaluation.

Blood in Your Stool

Any instance of blood in your stool should be investigated by a doctor.

Hemorrhoids are a common cause of rectal bleeding, but they can coexist with cancer. Thus, even when hemorrhoids are present, a doctor's evaluation is necessary when blood appears in bowel movements.

While X-rays might suffice in some cases, further studies may be required if the source of bleeding isn't evident.

Unexplained Anemia

Anemia, having fewer red blood cells than normal, demands investigation.

There are various types of anemia, but iron deficiency anemia is often due to blood loss unless there's a clear ongoing source like menstruation.

Bowel cancer is a common cause of iron deficiency anemia. Evaluation typically includes endoscopy or X-rays of the upper and lower intestines.

Breast Lump or Breast Discharge

Most breast lumps are benign tumors like fibroadenomas or cysts, but all lumps should be thoroughly examined.

A negative mammogram isn't sufficient to evaluate a breast lump.

Diagnosis often requires a needle aspiration or biopsy for a small tissue sample.

While breast discharge is common, certain types may signal cancer. Bloody or single-nipple discharge warrants further evaluation. Women are advised to perform monthly breast self-examinations.
