Meaning of Cancer

Before we proceed in this essay on cancer, we must understand cancer's meaning or what exactly is cancer? Cancer is the term given collectively to any and all forms of unregulated cell growth. Normally, the cells inside our body follow a definitive cycle from generation to death. However, in a person suffering from cancer, this cycle is unchecked and hence the cell cycle passes through the checkpoints unhinged and the cells continue to grow.

Types of Cancer

Now, that we have a preliminary understanding of the meaning of cancer, let us proceed to the cancer types or specifications. Cancer types are usually named after the area they affect in the body - usually like skin, lung, pancreas, blood, stomach among the others. However, if classified biologically, there are primarily five types of cancer. These include - leukaemia, melanoma, carcinoma, sarcoma, and lymphoma.

Leukaemia is the type of cancer that originates in the blood marrow and is a cancer of the blood. In this cancer type, no tumours are formed. Melanoma is regarded as one of the most dangerous types of cancer as in this, the skin colouring pigment or melanin becomes cancerous in nature. Carcinomas are cancers of the various types of glands such or organs such as the breasts, stomach, lungs, pancreas, etc. Cancers of the connective tissues such as the bones, muscles, etc are classified as sarcomas. Lymphomas, on the other hand, are cancers of the white blood cells. Among the most diagnosed types of cancers are carcinomas.

Cancer Causes

In the present day living environment, a number of factors are liable to cause cancer. However, in many cases, one single factor cannot be attributed or held responsible for causing cancer in an individual. The substances that are known to be cancer-causing or increasing the risks of cancer are known as carcinogens. Carcinogens can range from anything to pollutants to tobacco to something as simple as processed meats.

The effect of carcinogens, however, on different individuals is different and it is also dependent on a number of factors, be it physical, lifestyle-choice or biological. The physical factors enabling the effect of carcinogens include exposure to different environmental conditions such as UV rays, X-rays, etc. Cancer among mining workers because of their constant exposure to asbestos and fine silicone dust is common. Biological factors generally include hereditary factors, such as the passing of a mutated BRCA1 or 2 mutations from mother to daughter in case of breast cancer. In addition, they also include factors such as age, gender, blood type, etc. Lifestyle-choice refers to habits such as smoking, drinking, radiation exposure, etc, which can act as triggers for carcinogens.

Cancer Treatment

In this segment of our essay on cancer, we will discuss the various types of cancer treatments involved and their applicability. The most commonly applied cancer treatments include surgery, chemotherapy and radiation therapy. Often, these treatments are given in a combination of one with the other. Surgery is usually performed in the case of benign tumours usually followed by a short cycle of preventive chemotherapy. The treatment of chemotherapy includes a combination of drugs targeted to kill cancer cells. Radiation therapy, on the other hand, makes use of radiations to kill cancerous cells. All these treatments are usually known to have side effects, so after-care for cancer survivors is also equally important.

The kind of treatment best suited for a patient is usually determined by the physician. The most important aspect of cancer treatment is early diagnosis and immediate medical intervention. The chances of surviving or beating cancer increases by a paramount value if diagnosed in the early stages.

Cancer Awareness

In India, and many other countries, speaking or discussing cancer is still considered taboo and this perception is in dire need of a change. Always remember cancer awareness is the first step towards cancer prevention. You must come across survivors sharing their journey by means of speech of cancer awareness. It can be of great benefit to know about the disease beforehand as it will keep you wary of any signs or symptoms you might come across and bring the same to the notice of your physician immediately. This will help in preventing or fighting cancer more effectively.

FAQ (Frequently Asked Questions)

Q1. Differentiate Between Cancerous and Non-Cancerous Tumours.

Ans. The unregulated cell mass inside the body is known as a tumour and can be specified to a particular area or the uninhibited cell growth may spread to the surrounding tissues. Based on this, tumours are majorly classified into two types:

Benign Tumours: This type of tumours are usually regarded as non-cancerous as they are specified to a particular area and can be surgically removed without causing damage to the surrounding tissue.

Malignant Tumours: These tumours, on the other hand, have broken free from their site of origin and spread to other tissues, usually through the bloodstream. These tumours are cancerous in nature and usually require other treatments.
