Relying solely on routine tests may not be enough to protect yourself from cancer. It is equally important to be in tune with your body and notice any unusual, strange or obvious symptoms. Here are some commonly overlooked signs that could indicate potential health problems:

Wheezing or shortness of breath: Difficulty catching your breath may be an early sign, especially for lung cancer patients.

Chronic cough or chest pain: Symptoms that resemble a persistent cough or bronchitis may indicate various cancers, including leukemia and lung tumors. Chest pain that radiates to the shoulder or arm is also worth noting.

Fever or frequent infections: These can be signs of leukemia, which disrupts normal white blood cell production and impairs the body’s ability to fight infection.

Difficulty swallowing: This symptom is associated with cancer of the esophagus or throat, and may also be an early sign of lung cancer.

Enlarged lymph nodes or masses: Changes in the lymphatic system, reflected in swollen lymph nodes, can indicate cancer.
