Over the past quarter-century, the U.S. has seen a 27% decrease in cancer fatalities. This progress is mainly due to declining smoking rates, technological breakthroughs, and better awareness. Detecting cancer early through symptom recognition is crucial for successful treatment. Here’s what everyone should understand about this disease.

What Is Cancer?

Cancer is not a single ailment but a collection of related conditions. Our bodies continually produce new cells while old ones die and are replaced.

In cancer, cells grow abnormally and multiply uncontrollably, leading to the formation of masses called tumors. These can be benign or malignant. Malignant tumors are cancerous and can invade nearby tissues or spread to other parts of the body.

Factors Influencing Cancer Risk

The exact cause of cancer remains elusive, but risk factors include genetics, environmental factors, age, lifestyle habits, and hormonal influences. While some risks like inherited traits are non-modifiable, others—such as smoking, diet, sun exposure, and obesity—can be managed or avoided.

Cancer Progression Stages

Cancer development is generally divided into four stages, with the TNM system providing detailed classification. The stages are typically:

Stage 0: Abnormal cells are detected but have not formed a tumor.

Stages 1-3: The cancer is present within the body, with gradually increasing spread to nearby tissues and lymph nodes.

Stage 4: The cancer has metastasized, affecting distant organs.

Methods to Reduce Cancer Risk

Adopt a healthy diet and active lifestyle

Monitor and treat precancerous conditions promptly

Explore chemopreventive options if at high risk

Consider preventive surgeries as recommended

Avoid known carcinogens and risk factors
