What is malignant neoplasms (cancer)?
Answer (2)
Malignant neoplasms, or cancer, are characterized by uncontrolled cell growth and can invade surrounding tissues. They arise from mutations, are influenced by genetic and environmental factors, and can spread throughout the body. Early detection and treatment are crucial for improving survival rates.

Malignant neoplasms, commonly known as cancer, refer to a class of diseases characterized by the uncontrolled growth of abnormal cells. These cells can invade and destroy normal body tissue and have the potential to spread throughout the body. Understanding cancer involves exploring various factors:
What? - Cancer arises due to genetic mutations that affect how cells grow and divide. Unlike benign tumors, which do not spread, malignant tumors can invade neighboring tissues and metastasize to distant parts of the body.
Why? - The exact cause of cancer is complex and often involves a combination of genetic, environmental, and lifestyle factors. Common risk factors include smoking, exposure to radiation, certain infections, and some genetic predispositions.
How? - The transformation from a normal cell to a cancerous cell typically involves multiple genetic changes. These changes can lead to the activation of oncogenes (genes that promote cell growth) or the inactivation of tumor suppressor genes (genes that control cell growth and apoptosis).
Diagnosis and Treatment - Cancer is typically diagnosed through a combination of imaging, laboratory tests, and biopsy procedures. Treatment options vary based on the type and stage of cancer and may include surgery, chemotherapy, radiation therapy, and immunotherapy.
Prevention and Early Detection - Lifestyle modifications, like quitting smoking and maintaining a healthy diet, can help lower the risk of developing certain cancers. Screening tests, such as mammograms and colonoscopies, are crucial for early detection and improving treatment outcomes.
Cancer research is ongoing, with scientists working to understand the biology of cancer better and to develop more effective treatments.
