The disease known as cancer is defined by the body’s aberrant cells growing and spreading out of control. Early detection is critical for improving treatment outcomes and survival rates, as many forms of cancer are more treatable when caught in their early stages. Unfortunately, early signs of cancer are often subtle and easy to dismiss. Paying attention to these early warning signs can help in catching cancer before it progresses. This article explores eight early signs of cancer growth that should not be ignored.

1. Unexplained Weight Loss

One of the most common early warning signs of cancer is sudden weight loss. While weight fluctuations can be normal, losing a significant amount of weight without changing your diet or exercise habits can be a red flag. Many cancers, including those affecting the stomach, lungs, pancreas, and esophagus, can cause sudden weight loss. This occurs because cancer cells use up a lot of the body’s energy or because they produce substances that alter the body’s metabolism. If you’ve lost 10 pounds or more without trying, it’s worth consulting a doctor.

2. Persistent Fatigue

Fatigue that does not improve with rest or sleep is another potential early indicator of cancer. Unlike normal tiredness, cancer-related fatigue is often extreme and doesn’t resolve after a good night’s sleep. This type of fatigue may be caused by the cancer itself, which drains the body’s energy, or by the body’s response to cancer, such as the production of inflammatory substances. Cancers like leukemia, colon cancer, or stomach cancer can cause persistent fatigue in their early stages.

3. Changes in the Skin

The skin can offer early clues to what is happening inside the body. Skin changes, such as new moles, sores that won’t heal, or changes in existing moles (shape, color, or size), can be signs of skin cancer, including melanoma. Additionally, other types of cancer can cause skin changes, such as darkening of the skin, jaundice (yellowing of the skin and eyes), or unexplained redness or itching. These changes, especially when they appear suddenly or worsen over time, should be evaluated by a healthcare professional.
