I need some assistance with these assignment. characteristics of cancer Thank you in advance for the help! These neoplastic cells continue to multiply, independent of any physiological growth regulated stimulus and doing so, they increase in size and number, and usurp the nutrition of the cells in that region, causing complications.

They are classified as benign or malignant based on their physiological interaction on the cellular level and have different approaches to their treatment. The nature of this disease is such that it may take up to ten years from exposure to detection for a particular type of cancer.

Although medical science has made many strides in the field of oncology and most cancers can now be treated by a number of different approaches including surgery, chemotherapy, hormone therapy, radiotherapy and targeted therapy, it has failed to contain the spread of this disease due to lack of social awareness and unhealthy lifestyles that govern the incidence and epidemiology of this disease, particularly in the developing and poor countries. Therefore, there is a significant influence of environmental, geographical and sociological factors upon the growth and development of cancers in our societies.

Tumors are primarily classified as Benign or Malignant, however, they have certain componential similarities, namely the parenchyma, which is made up of transformed cells and the stroma, which consists of connective tissue, blood vessels and inflammatory cells taken over from the host.

Malignant tumors are those that can spread from their origin to multiple sites in the body to cause death. The process of proliferation is known as ‘Metastasis’ and is a defining characteristic of this type of tumor. Not only do they metastasize (bone sarcomas), but malignant tumors are also highly invasive (basal cell carcinomas and primary CNS tumors).

They also have variation in the aggressiveness of their spread, and a wide degree of parenchymal cell differentiation which makes their identification difficult and therefore, has to be treated accordingly.
