Cancer happens when abnormal cells of the body grow beyond the control in our bodies. According to medical science, there are over 200 types of cancer. General categories or causative reasons for cancer-related are as follows: chemical or toxic compound exposure, ionizing radiation, some pathogens, and human genetics. Whatever that may cause a normal body cell to develop abnormally potentially that may cause cancer. And these abnormal cells are termed as malignant cells, tumour cells, or cancer cells. Not only human beings even animals or any other living organisms can get cancer.
The three most common cancers noticed in men, women, and children are as follows:
- Men: prostate, lung, and colorectal cancer.
- Women: breast, lung and colorectal cancer.
- Children: leukaemia, lymphoma, and brain tumours.
Stages of cancer
According to medical science cancer co-relates to one of the following five stages.
- Stage Zero: In this stage, the cancerous cells are confined to their site of origin. In this stage, cancer doesn’t spread and invade other tissues.
- Stage One: Stage Three: These are generally advanced stages of cancer. This step correlates to large tumours. The cancerous cells may have spread beyond the site of its origin in which it developed to nearby lymph nodes, organs adjacent to the location of the primary tumour.
- Stage Four: In this stage, cancer has spread to distant lymph nodes, tissues, organs in the body, and they are far away from the origin. In short, cancer has,’ metastasized’.
Some cancers which are related to the brain, spinal cord, bone marrow (lymphoma), blood (leukaemia), and female reproductive system are classified according to different staging system.
Symptoms and signs/changes in a routine pattern
Cancer is the second most common disease which can cause death after heart disease. Basically, cancer gives no symptoms that exclusively indicate the disease very fast. Although there are some common symptoms that may occur such as following:

However, a best cancer doctor in India ought to be seen for any conclusion.
The most common tests used to diagnose cancer are as follows:
Mammogram, Pap test, Tumour maker test, Bone scan, MRI, Tissue biopsy, PET-CT scan.
Types of cancer
There are over 200 types of cancer. Some specified types of cancer are most commonly found in general categories. Some of them are as follows:
- Carcinoma: this type of cancer generally originates in the skin or tissue that line or cover internal organs.
- Sarcoma: This type of cancer starts in bone, cartilage, fat, muscle, blood vessels or other connective or supportive tissue.
- Leukaemia: This cancer starts in blood-forming tissue like bone marrow, and it causes a large number of abnormal blood cells to be produced and enter into the blood.
- Lymphoma and malignant tumour: this kind of cancer begins within the cells of the system.
- Central nervous system cancer: Cancer that is originated from the tissue of the brain and spinal cord.
Many types of cancer treatments in India are available nowadays all over the world. Which kind of treatment you will receive depends upon the type of cancer and its stage. For some people having cancer only one type of treatment is enough but the most time people need combination treatment like surgery with chemotherapy or radiation therapy. In India,cancer hospital in Delhi is well-known. Except that Mumbai, Bangalore, Kolkata, and Thiruvananthapuram are also known for the best cancer treatment. The cost of cancer treatment can go up to 20 lakhs in India and 40000 US dollars abroad.Some types of cancer are really curable, it doesn’t matter when they are detected, and otherwise, some of them are curable only in the early stage of this disease.
