TopIntroduction
A disease is termed to be Cancer when the abnormal cells divide rapidly. The cells start to divide at a slower pace and spreads to the surrounding tissues thereby affecting other organs gradually. Cancer can start in any part of the body and contains a trillion of affected cells. Regularly, human cells develop and forms the new cells as the human body requires them. The formation of new cells and the dead cells getting regenerated follows a continuous process. When Cancer effects a specific part of the body, this continuous process breaks down.
The unnecessary abnormal cell development is grouped as tumours. Many tumours are strong with a mass of abnormal tissues. A type of Cancer called Leukaemia is not a strong tumour.
There are 2 types of tumours namely malignant and benign tumours. In malignant type of tumours, the cells spread from the actual side to more farther organs and spreads rapidly. Whereas, benign tumours do not spread to different parts of the body or the lymph system, and it is concentrated in a specific organ and can grow at the origin. It can be operated and the affected organ can be removed and does not grow back. Whereas, in malignant tumours, there are chances of cells growing again.

Types of Cancer include:
- a.
Carcinoma: The cells comprising of inner and outer body are called epithelial cells, the type of cancer causing these cells are called Carcinoma.
- b.
Sarcoma: These types of cancers affect the bones and soft tissues comprising of lymph nodes, blood vessels etc.
- c.
Leukaemia: They are also called as blood cancer. They effect the blood forming bone marrow in the human body. They stop the formation of red blood cells by excessively producing white blood cells.
- d.
Lymphoma: These are Cancer in the lymph nodes of the body. They develop by affecting the lymphocytes.
Taking the discussion further with respect to such a disease, it is a life risking tumour commencing by unstoppable cell growth in lung tissues. By metastasis, they can grow rapidly and spread faster to the surrounding tissues, Hence, causing more damage to the nearby organs. Most malignancies that start in the lung are known as essential lung Cancer, are carcinomas. The major symptoms are weight loss, difficulty in breathing, and regular chest aches. By far, the lung cancer is usually caused my consistent tobacco use for long periods of time in about 85% cases. Around 10-15% of lung cancer cases are shown in people who have never smoked. These cases involve the group of people who have been exposed to climate change, pollution, inhalation of radon gases, untreated smoke from industries etc. Lung cancer can be seen on CT scans and various other scans. Further to the scan, biopsy of the affected area is taken for further clinical testing and to conclude the malignancy.
Some of the other scanning types have been mentioned below:
- 1.
CT Scan: Also known as Computed Tomography, it is used to scan the cross section of a cell of specific organ using various combination of X-ray. It helps in learning the status of cancer by using external methods without using the method of slicing the internal part.
- 2.
PET Scan: Also known as Positron Emission Tomography (PET), is a scanning technique which uses radioactive substances.
- 3.
X-Ray: A photographic or digital image of the composition of the internal body part produced by a type of specific wavelength waves called X-rays which can be absorbed and can portray the affected organ.
- 4.
MRI Scan: Also known as, Magnetic Resource Imaging, this medical technique is used to picturise the anatomy by using strong magnetic fields to generate images of the organ.
