An Overview of Cancer

Care. Cure. Compassion

Cancer is a dangerous disease that affects the entire cells of the body. There are billions of cells in the human body that build together to form tissues. Cancer occurs when the abnormal and unusual cells multiply and spread very quickly.

What is cancer? 


Mitosis Vs Metastasis 

The normal cells in humans divide, grow and stop after a certain size but they will never die is the mitosis whereas the cells that continue its growth, create a new tumour and spread cancer to other parts is metastasis.


The cancerous Malignant tumours  

Malignant tumours are cancerous causing threat to life damaging the nearby tissues and organs. In this type, the cancer cells break away and move through the bloodstream or lymphatic system to form tumours in different parts of the body. 


The non-cancerous Benign tumours 

Benign tumours are non-cancerous and are rarely a threat to life.  It can be removed and it will stop its damage by not spreading to other parts of the body and also doesn’t invade other tissues.


Other common types of cancer 

There are general categories of cancer based on the cell type. Carcinomas and adenocarcinomas are more specific and most common types of cancer.  The other categories include brain cancers, nerve cancers, melanomas, and certain ovarian and testicular cancers.


Carcinomas Vs Adenocarcinomas  

Carcinomas are cancers that form solid tumours and start in epithelial surfaces, to line or cover the body's organs, tubes, cavities, and passageways.  Adenocarcinomas are a subtype of Carcinomas which starts in glandular tissues to form mucus or fluid. 


Sarcomas, Leukaemia and Lymphomas 

Sarcomas start in cells that make up supporting structures, such as bone, cartilage, muscle, fat, or fibrous tissue.  Leukaemia starts in the blood cells, most often white blood cells.  Lymphomas starts in cells of the lymph nodes and lymphatic system.


Detecting the signs of cancer 

– A lump  – A change in the skin – Persistent sore throat  – Change in bowel and bladder    movement – Persistent cough  – Trouble swallowing and indigestion – Vaginal discharge or unusual bleeding – Chronic fatigue


Consulting a physician  for treatment

It is always good to see your family physician right away because the exact cause of cancer is still somewhat a mystery, as cancer is not contagious.   Unhealthy habits like smoking and excess drinking can increase the risk of getting cancer.
