What Is Cancer

Cancer is the name of the collection of diseases. Cancer is a term for a large group of diseases characterized by the development of abnormal cells beyond their normal boundaries, which can then attack parts around the body and/or spread to other organs. In all types of cancer, some cells of the body begin to break without pausing and spread to surrounding tissues.

Cancer can start almost anywhere in the human body, which is made up of trillion cells. Generally, human cells grow and divide to form new cells because the body needs them. When cells become obsolete or damaged, then they die, and new cells take their place.

Cancer is the second leading cause of death globally and in 2018 deaths of 9.6 million people are estimated. The most common types of cancer in lungs, prostate, colorectal, stomach and liver cancer are in men, whereas breast, colorectal, lung, cervical and thyroid cancer is the most common among women. When cancer develops, cells become more abnormal, old or damaged cells survive when they should die, and new cells are formed when they are not needed. These extra cells can be divided non-stop, and can form tumors.

Many cancers form solid tumors, which are mass of tissue. Blood cancers, such as leukemia, usually do not form solid tumors.

Signs Of Cancer

Changes in your body's normal processes or abnormal, unexplained symptoms can sometimes be the initial sign of cancer.

Symptoms to be checked by the doctor include:

• A lump that suddenly appears on your body
• Unexplained bleeding
• Changes in your bowel

But in many cases your symptoms will not be related to cancer and others will be due to non-cancer health conditions.

Cancer prevention

According to the evidence, preventing cancer deaths from 30% to 50% or preventing major risk factors:

• Avoiding tobacco products, 
• Reducing alcohol intake, 
• Maintaining healthy body weight, 
• Exercising regularly and transmitting,

The related risk factors can be prevented from addressing.

Cancer Treatment

Surgery is the first treatment to try for most types of cancers, because solid tumors can usually be removed by surgery.

The two other commonly used treatment methods are:

• Chemotherapy 
• Radiotherapy 

Types of cancer

There are more than 100 types of cancers. Types of cancers are usually named for those organs where the cancer is formed. For example, lung cancer begins in lung cells, and brain cancer cells begin in brain cells. Cancer is also described by the type of cell.

Here are some categories of cancers that start in specific types of cells:

• Carcinoma
• Sarcoma
• Leukemia
• Lymphoma
• Multiple Myeloma
• Melanoma
• Brain and Spinal Cord Tumors

Other Types of Tumors

• Germ Cell Tumors
• Neuroendocrine Tumors
• Carcinoid Tumors
