Cancer and cardiovascular diseases

Several experiments have been conducted on oncology by using animals in several laboratories and have proposed the life of the cancer in three ways. Cell biology, where the cancer cell starts its growth from the normal cell due to the immortal cell that is highly independent which leads to the further development of cancer in the human body. Molecular biology can be precisely described as the changes in the DNA which leads to pre-cancer followed by the formation of cancer and finally it attains the state of metastasis. The final model proposed for the life of the caner is that hyperplasia where the production of cell is enormous which undergoes the process of carcinogenesis which then invades the nearest normal cells and becomes as a metastatic cancer. The experimental data provide further information about the cancer in a clear view.

From the perspective of cancer it is clearly susceptible that prevention is always better than cure. Numerous awareness programs have been organised by the government and several other organisation for the benefit of the people where it reveals to stay free from the smoking, exposure to ultra violet radiations and other stuffs that can affect the human body. Of course due to the other causes cancer can also be cured by means of certain treatments like surgery, chemotherapy, radiotherapy, immunotherapy etc. however early detection of cancers are highly important for the positive responsiveness of these treatments. The number of cells affected is proportional to the probability of curing the cancer. The early treatments involve extensive surgery which removes the tumour cells from the affected region and prevents it from invading the other regions. There are some cancers like breast, cervical and colorectal cancer where early detection of inception of cancer cells will increase the success rate of the treatment.

It is proven that the cardiovascular disease are more common than the cancer but still people think that cancers are incurable and it always leads to death. The researchers have also proclaimed that cardiovascular disease is more common for people in young age whereas when it comes to cancer affects commonly on people of high age other that leukaemia. Death in cancer is too frequent but still there are some cancers which can be cured based on the region it has been affected and the sages of the tumour in its growth. Likewise the victim for breast cancer which is common among women is estimated to thirty percentages but still it accounts only seventeen percentages of deaths. The specifications are more or less similar to the caner in the uterus also. Although death is more common in cancer but still it depends on the area of invasion such as brain and liver and moreover if it is diagnosed at the early stage it can be cured.

The significant property of the cancer cells is the ability to spread to the other regions of the organs through invasions. The growth of the cell in a single region due to the accumulation of cells forming a mass structure can be considered to be a benign and may not be exactly a cancer. Some changes are being stimulated which enables those cells to invade the nearest cells and metastasise to the other regions of the body. This is the emphasised ability of the cancer cells were it overcomes the normal mechanism of the cell which resulting in diminished cell. The exclusive feature of the cancer cells is that it sends message signal to normal cells to help them. By sending these signals the cancer cell makes them promote new blood vessels which give them adequate supply nutrients for its growth. This property of acquisition of newer cells differentiates the cancer cells from the normal cells.

It is clear that some genes in the human body are highly responsible for the growth of the odd cells in the body and also its proliferation. These genes are called as oncogenes and these are the genes that are responsible for the causes of cancer. These genes have the capability of proliferating itself as it has the capability of independency. These genes once secreted in the human it has the capability of mutation which deregulates the normal cell functionality. The next factor that is responsible for the growth of the cancer cell in the human body is tumour suppressor genes. This is another factor where the cancer will be generated in the human body due to the loss of specific genes in the human body concerned with the repair of cell damage, cell death or growth inhibition. These are the primary genetic factors that are responsible for the causes of the cancer.
