Finally I will discuss the treatment for cancer. Cells can experience uncontrolled growth if there are damages or mutations to DNA, and therefore, damage to the genes involved in cell division.
Cancer begins to form when the process of programmed cell death called apoptosis breaks down. The growth of multicellular animals occurs due to addition of new cells. Be active and maintain healthy weight.
Four key types of gene are responsible for the cell division process: In cancerous cells the controlling factor is not present, probably due to mutant genes.
For example, a lump on the breast or testicle can be an indicator of cancer in those locations.
Unusual bleeding or discharge of blood. In such cases, tumour development is recessive to normal development, and both the alleles must be inactivated by mutation or deletion to allow oncogenesis. There are a group of genes whose inactivation loss-of -function by mutation, including deletion leads to tumour formation; these are known as Tumour Suppressor Genes.
Onkos meaning cancer were initially identified as genes carried by viruses that cause transformation of their target cells. Though the exact cause of cancer is not known, the above described substances are mutagens which can cause mutation in genes.
These genes usually impose some restriction on the cell cycle or cell growth. What exactly is Breast Cancer? Therefore a loss-of- function for such genes is tumorigenic.
Chewing of tobacco, betel nuts etc. Some brain tumours tend to present symptoms early in the disease as they affect important cognitive functions.

For example if there is cancer growth in your prostate and it parades to another part of your body, it would be classified as prostate cancer, although the cancer has spread to another part of your body, it only counts where the cancer originated from.
Transition: (Next, I will talk about ways to prevent cancer from forming.) 2. Cancer has become the second-most killer disease today, killing about seven to eight million people every year in the world.
It refers to a class of diseases characterized by out-of-control cell growth. There are over different types of cancer, and each is classified by the type of cell that is initially affected. Informative Essay About Cancer Words Nov 13th, 3 Pages Cancer is a word that no one wants to hear or think about, however there are many people that are faced with this ugly word every day.
Excessive smoking has been found to be associated with lung cancer, cancer in urinary bladder, mouth, throat, larynx etc. 2. Chewing of tobacco, betel nuts etc. are believed to be the cause of cancer in mouth, throat, oesophagus etc.
