Cancer Symptoms: Cancer is one of the leading causes of death globally, affecting millions of individuals every year. Early detection of cancer is crucial for successful treatment and survival, and for this to be done, everyone should have proper knowledge about the warning signs associated with cancer. As we observe World Cancer Day 2025, it's an important opportunity to raise awareness about the symptoms of cancer that shouldn't be ignored.

In this article, we understand the top 10 most common, yet often ignored signs and symptoms of cancer in both men and women.

10 Most Common Signs of Cancer That Shouldn't Be Ignored

Here are the top 10 most common signs associated with cancer that shouldn't be ignored at any cost:

Unexplained Weight Loss

Even though a sudden and unexplained weight gain is associated with several health complications, one of the most common one is CANCER. Studies have shown that losing weight suddenly without trying or dieting, especially more than 10 pounds, could be an indicator of several types of cancers, such as stomach, pancreatic, esophageal, and lung cancer.

Extreme Fatigue And Tiredness

When your body has already developed cancer cells, it becomes difficult for you to feel energetic. Yes, you read that right! Feeling constantly tired or fatigued is another potential warning sign of cancer.

Some of the cancers that can cause excessive fatigue are leukemia, colon cancer, or stomach cancer.

Changes in Skin

A sudden and unexplained change in your skin texture, or colour is another warning indicator of cancer, especially skin cancer. You may notice a new mole, skin tags getting bigger, or even red patches on the skin --- all of these indicate melanoma, a type of skin cancer.

Persistent Cough or Hoarseness

A persistent cough or hoarseness that lasts more than a few weeks is a clear indicator of lung cancer, although it could also be a sign of throat, larynx, or esophageal cancer. Studies have shown that this type of cough (in cancer patients) can lead to the production of blood, phlegm, or mucus. It may also lead to chest pain.

Unexplained Pain And Discomfort

A patient suffering from cancer may notice certain difficulties while swallowing along with unexplained weight loss or persistent pain. Never ignore this and make sure to visit a doctor immediately.

Lumps or Thickening in the Breast or Other Areas

Lumps or thickening in the breast, neck, underarms, or testicles should always be examined by a doctor. Breast cancer is often the first thing that comes to mind when women notice changes in the breast, but men can also get breast cancer. A lump in the breast or changes in the texture or appearance of the breast tissue, such as skin dimpling, should be evaluated.

Unusual Bleeding or Discharge

Unexplained bleeding or discharge can be a sign of several types of cancer. Cervical cancer and endometrial (uterine) cancer may cause abnormal vaginal bleeding, particularly after menopause or in between periods. Colon cancer might cause rectal bleeding, which could result in blood in the stool. Unexplained coughing up blood could indicate lung cancer.

Digestive Problems

While digestive problems have been linked to several health problems, one of the most dangerous ones is cancer. Yes, that's right! Persistent or worsening digestive problems, such as bloating, nausea, vomiting, or a feeling of fullness after eating only a small amount of food, can be signs of stomach cancer, ovarian cancer, or pancreatic cancer.

Beware of all the signs and symptoms of cancer mentioned-above. If you notice any of the symptoms mentioned above, consult a healthcare professional for further evaluation. Remember, taking action early can make all the difference in the outcome of treatment. Stay vigilant, stay healthy, and don't wait for symptoms to get worse.
