What is Cancer?

First we need to understand what is Cancer?

Cancer is a group of fatal diseases that mutates genes encoding critical cell-regulatory proteins; resultantly the aberrant cell behavior leads to extensive masses of abnormal cells that destroy all the surrounding normal cells and tissues and then spread to vital organs. Likewise, the disease disseminates faster and cause patient death.

Cause of Cancers:

More than 30 percent cancers are caused by several leading behavioural and environmental factors. Tobacco is one of the largest causes of cancer across the world.

However, following are the significant causes of cancers:

  • Tobacco
  • Alcohol
  • Unhealthy diet (especially insufficiency of fruits and vegetables)
  • Overweight
  • No physical exercise
  • Chronic infections from helicobacter pylori, hepatitis C virus (HCV), hepatitis B virus (HBV), and some types of human papilloma virus (HPV)
  • Environmental and occupational risks, such as ionizing and non-ionizing radiation

Some types of cancers’ (such as pancreas cancer) are symptoms are very typical and do not appear until cancer grows very big. Anyway, as a cancer grows, it begins to affect nearby organs as well including blood vessels and nerves. It leads to some symptoms of cancer. So, as cancer keep growing its symptom is becoming pervasive (many parts of the body) and affecting the health critically.

Moreover, some of the common symptoms (not necessarily, therefore better to get diagnosed) are:

Diagnosis of Cancer:

Primarily, symptoms of cancer are not much perceptible and identifiable; therefore, proper medical diagnosis is the best way to identify the particular stage of cancer.  There are different ways of diagnosis of cancer; however, it depends largely upon the type of cancer. Later, while dealing the particular type of cancer, we will learn the particular type of cancer diagnosis.

Treatment of Cancer:

Treatment of cancer is very typical that needs the following types of treatment and care:

  • Surgery
  • Radiotherapy
  • Chemotherapy
  • Psychological support

However, if the cancer is detected at its early stage, it can be cured, to and some extent completely. Many of the cancers including Breast Cancer, Oral Cancer, Cervical Cancer, and Colorectal Cancer have higher rate of successful cure.

Besides, other types of cancers have also high cure rate provided, it is detected at its early stage and proper treatment given.

Preventive Measures:

Following are the significant preventive measures that protect from the cancer disease:

  • Tobacco Control
  • Promotion of Healthy Diet
  • Physical Exercise
  • Limited use of alcohol
  • Protection from the exposure to avoid infectious agents associated with cancer
  • Vaccination against Hepatitis B Virus and Human Papilloma Virus
  • Promotion of protective actions, to carcinogens in the environment and workplace, including ionizing and non-ionizing radiation
