Cancer is often known as a silent killer because most of the time the symptoms are unspecific or subtle. Some symptoms of cancer are common in nature. However, people generally ignore these signs by believing they are less serious health conditions. 

In this blog, we’ll dive more into the main cancer symptoms that shouldn't be ignored! Detecting some of the cancer symptoms can be life-saving.

Why early detection matters in the treatment of cancer?

According to the WHO, early cancer detection significantly increases the chances of successful treatment, and it improves the survival rates of several cancer cases. Studies suggest that when cancers are diagnosed in the early stages, they can be curable and highly treatable.

Common cancer symptoms you shouldn’t ignore!

There are some common cancer symptoms people shouldn’t ignore. However, early detection can enhance the chances of a successful treatment outcome and improve the overall quality of life.

If you are experiencing any of these symptoms, it doesn’t mean you have cancer. But early detection can save lives. If you are experiencing any of these symptoms for more than two weeks, then consult a doctor!

Here are some of the signs, including:

Sudden weight loss

One of the common symptoms of cancer is losing weight without even trying. If you are experiencing unexplained or unintentional weight loss, especially more than 5 kg in a short period of time. This is a great sign and often considered as a first sign of cancer.

Some types of cancer that have a symptom of weight loss include:

  • Pancreatic cancer
  • Stomach cancer
  • Esophageal cancer
  • Lung cancer

Continuous fatigue or tiredness

If you are experiencing extreme fatigue that doesn’t get better even after taking enough rest. It can be a major sign of cancer because the body is sending signals that show that something is not normal.

If you feel persistent fatigue, it indicates abnormalities in the body, which needs quick attention. 

Some of the cancer that has the same symptoms, including

  • Leukemia
  • Colon cancer
  • Stomach cancer
  • Any advanced-stage cancer

Chronic pain

Pain is one of the common symptoms of cancer. However, it can happen due to several health issues. While most cases are not usually related to cancer. A continuous and constant pain also indicates an underlying disease in the body.
