The most common disease which takes hundred & thousands of lives every year is the CANCER .
When our body cells (structural unit of life) starts growing abnormally is Cancer. Human body is made up of trillions of cells, so, It can almost start anywhere in the human body. Normally when cells grow & become old, they die & new cells takes their place. But during cancer this process breaks down & the old cells will survive & new cells will form when they are not needed, these extra cells can divide without stopping & form growths which is called TUMORS (related to mass).
There are three types of tumors –
Difference between Cancer cells & Normal cells :-
How cancer arises & spread :-
Cancer is a genetic disease which is caused by the changes in the DNA (genetic material of our body). We can get these changes from our parents or they can also arise during a lifetime of a person due to some environmental or outside exposure like tobacco, smoke, & radiation such as UV rays from the sun.
In general cancer cells have more genetic changes (mutations in DNA) than normal cells.
These genetic changes can affect three types of genes – Proto-oncogenes , Tumor suppressor genes & DNA Repair genes.
Proto-oncogenes helps in normal cell growth and division. However, when there is any change in these genes they can become cancer causing genes (or oncogenes), allowing cells to grow and survive when they should not.
Tumor suppressor genes also helps in controlling cell growth and division. Cells with some changes in tumor suppressor genes may divide in an uncontrolled manner.
DNA repair genes helps in fixing damaged DNA. Cells with changes in these genes can add to the changes in the other genes. Together, these mutations may cause the cells to become cancerous.
When the cancer cells break away & start spreading in the body with the help of blood or lymph system & form new tumors, this process is called Metastasis (Metastatic cancer).
Types of cancer :-
There are more than 100 types of cancer. They are usually named after the organs or tissue where the cancer has been formed. The most common types of cancers are:-
The person with lung cancer have symptoms like coughing (with blood), chest pain, wheezing (breathing with whistling sound in the chest) etc.
The person with lung cancer have symptoms like red patches on the skin, unusual growth etc.
It shows symptoms like lump in the breast, changes in the shape & texture of the nipple or breast.
It shows symptoms like weight loss , yellowish skin (jaundice), vomiting etc.
It shows symptoms like blood in the urine, lump in the abdomen, fatigue, loss of appetite etc.
Risk factors for Cancer are:-
Types of cancer treatment are:-
Surgery can be without cuts like -
Surgery can be of two types:-
Radiation therapy is oftwo types :-
It can be given in many ways:-
As scientists & researchers are doing efforts to kneel down this disease there are lots of Recent developments in cancer treatment :-
As cancer is not the single diseases, it is a class of diseases which can occur in anyone irrespective of their age. So, there may be chances that single treatment is not fully effective combination of treatments can be done & it is necessary that joint efforts of all the countries are made to do more & more research & development in the cancer related treatments.
