Cough, cold and persistent flu-like symptoms are common, especially during seasonal changes. Most often, these are caused by viral or bacterial infections. However, in rare cases, what seems like a routine cold may be an early sign of something more serious, such as cancerSome symptoms may seem like a cold but persist or worsen over time, requiring medical attention as it could lead to a serious illness such as cancer. Here are five signs that may indicate cancer.

A prolonged cough, especially one lasting more than three weeks, may be a warning sign. According to the American Cancer Society (ACS), a chronic cough, especially if accompanied by blood or changes in the voice, may be a sign of lung cancer or throat cancer. Studies show that 57 percent of patients with early-stage lung cancer complain of a persistent cough as their first symptom. If cough doesn’t respond to common treatments, it’s time to consult a doctor.

While losing a few pounds may seem like a success, losing weight without even trying can be a red flag. A study published in the British Journal of General Practice showed that unexplained weight loss could be a sign of certain cancers such as stomach, pancreas, esophagus and lung. When the body is fighting cancer, it burns more calories, which can lead to rapid weight loss even if dietary habits remain unchanged.

Illnesses like colds or flu that recur again and again may not just be a weak immune system. The American Society of Hematology says that frequent infections can sometimes indicate leukemia, a cancer of blood-forming tissues. Leukemia impairs the body’s ability to produce functional white blood cells, leading to repeated relapses. If you notice frequent fevers or infections for no apparent reason, a thorough medical evaluation is necessary.

Fatigue is a symptom of many conditions, including colds and flu. However, cancer related fatigue Often severe and does not improve even with rest. The National Cancer Institute (NCI) states that cancers such as leukemia, lymphoma, and colorectal cancer can cause fatigue due to changes in the body’s immune response and metabolism. If you feel persistent fatigue even after getting enough sleep, it may require further investigation.

A sore throat that persists for several weeks or difficulty swallowing food may be a sign of cancer of the throat or esophagus. A study in the International Journal of Cancer found that persistent throat problems are one of the early symptoms of these cancers. Pay attention if swallowing hurts, food feels “stuck,” or you notice hoarseness that won’t go away.

Not every long-lasting symptom is a sign of cancer. However, the American Cancer Society recommends that any symptoms that persist for more than three weeks or worsen over time should be evaluated by a health care professional. A detailed medical history, imaging, and blood tests can often identify the cause.

Although you can’t prevent all cancers, certain lifestyle changes can reduce your risk.

– Quit smoking: Tobacco consumption is a major cause of lung and throat cancer.

– Maintain a healthy weight: Obesity is linked to several cancers, including esophageal and pancreatic cancer.

– Limit alcohol intake: Excessive drinking increases the risk of throat and liver cancer.

– Get regular checkups: Regular checkups, such as mammograms or colonoscopies, can detect cancers early when they are most treatable.
