What Happens In Cancer? | Symptoms, Causes And Types Of Cancer

Показать описание

Cancer is a life-threatening disease that often causes fear, but early diagnosis can make treatment easier. It is the second leading cause of death worldwide, following cardiovascular diseases.

In our bodies, DNA controls cell activities, including growth and lifespan. Cancer occurs when DNA mutations cause cells to grow uncontrollably and avoid programmed cell death (apoptosis). This leads to the formation of tumors.

When cancer is localized to a tumor, it is termed malignant and is generally easier to treat if detected early. However, if left untreated, cancerous cells can spread (metastasize) to other body parts through the lymphatic system or blood, making treatment more difficult.

Cancer affects the body by disrupting normal cell functions, leading to symptoms like unexplained weight loss, persistent fatigue, pain, night sweats with fever, and bleeding.

For accurate diagnosis and effective treatment, consult a doctor if you experience these symptoms. Check out our videos for more details on cancer diagnosis and treatment procedures.
