Everything you needs to know about cancer


Cancer disease is caused by the abnormal growth of cells in the body. These cells, called malignant cells, can invade nearby tissue and spread to other body parts through the bloodstream and lymph system. 


There are many different types of cancer, each with its specific characteristics and treatment options.


The most common types of cancer include:


Lung cancer: cancer that forms in the lung tissue

Breast cancer: cancer that forms in the breast tissue

Prostate cancer: cancer that begins in the prostate gland

Colon cancer: cancer that starts in the colon or rectum

Leukemia: cancer that begins in the blood cells

Skin cancer: cancer that starts in the skin cells

Bladder cancer: cancer that begins in the bladder

Ovarian cancer: This cancer starts in the ovaries

Pancreatic cancer: cancer that forms in the pancreas

Thyroid cancer: cancer that begins in the thyroid gland


Symptoms of cancer can vary depending on the type and stage of cancer. 

Some common symptoms include:


  1. Persistent fatigue
  2. Unexplained weight loss
  3. Pain
  4. Lumps or masses
  5. Changes in the skin, such as color or texture changes
  6. Changes in bowel or bladder habits
  7. Persistent cough or difficulty breathing


Treatment options for cancer vary depending on the type and stage of cancer. 

Some common treatments include:


Surgery: removal of the cancerous tissue

Radiation therapy: use of high-energy radiation to kill cancer cells

Chemotherapy: use of drugs to kill cancer cells

Immunotherapy: use of drugs to boost the body's immune system to fight cancer

Targeted therapy: use of drugs to target specific molecules in cancer cells


Frequently Asked Questions about Cancer:


What causes cancer?

Explain types of cancer


There are several types of cancer, each with its specific characteristics and treatment options. Some of the most common types of cancer include:


Carcinomas: This type of cancer originates in the epithelial cells, which are the cells that line the surface of the body's organs and tissues. Carcinomas include cancers such as breast cancer, lung cancer, and colon cancer.


Sarcomas: This type of cancer originates in the connective tissue, such as bone, muscle, and fat. Sarcomas include cancers such as osteosarcoma and liposarcoma.


Leukemia: This cancer originates in the blood cells and bone marrow. Leukemia can be either acute or chronic and affect both children and adults.


Lymphomas: This type of cancer originates in the lymphatic system, a network of vessels and organs that help fight infection and disease. Lymphomas include cancers such as Hodgkin's lymphoma and non-Hodgkin's lymphoma.


Melanomas: This type of cancer originates in pigment-producing skin cells called melanocytes. Melanomas are the most dangerous type of skin cancer.


Central nervous system (CNS) cancers originate in the brain and spinal cord. CNS cancers include cancers such as gliomas and meningiomas.


Germ cell tumors: This type of cancer originates in the cells that produce eggs or sperm. Germ cell tumors include cancers such as testicular cancer and ovarian cancer.


Each type of cancer has unique symptoms, causes, and treatment options. It is essential to consult with a medical professional for a proper diagnosis and treatment plan.
