Normally, the growth of the cells in the body is controlled by the body. When cells become old or damages, they are replaced by the new ones. But when the cells in the body starts to grow in an uncontrolled way, then become cancerous.
When the cells in the body don’t grow or divide in usual way, it causes the blood in the body to become abnormal, resulting in the development of tumour. Tumours is basically of two types:
- Benign tumour - This means that the cells are confined to one part and are unable to spread to other parts of the body.
- Malignant tumour - This means that the cells have the ability to spread to other parts of the body.
Cancer is a life threatening condition whose prevalence is high throughout the world. The diagnosed cases of both men and women are very high. There are many diseases that a large number of men suffer from
Prostate cancer is one of most common type of cancer in men. Any men can suffer from prostate cancer, but most often men over the age of 50 are more likely to suffer from this type of cancer. Only men has a prostate. It is a small gland which lies near the bladder and is responsible for making semen.
Prostate cancer occurs when there is a growth of cancerous cells in the prostate. Prostate cancer is of two types:
- Localised prostate cancer - Cancer that do not spread outside prostate is known as localised prostate cancer.
- Metastatic prostate cancer - Cancer that spreads to other parts of the body, outside prostate is known as metastatic prostate cancer.
Most prostate gland grows slowly and may not cause much problem, but sometimes prostate cancer grows quickly and are more likely to spread to other parts of the body, resulting is serious symptoms. Some of the common symptoms of prostate cancer include difficulty to start or stop peeing, pain while urinating, pain during sexual intercourse, and pain in the back. Prostate cancer is very common and many men throughout the world suffer from this type of cancer.
Lungs are one of the most important organ in the body which is responsible for multiple important functions in the human body. Lung cancer occur when the cells in the lungs becomes cancerous due to their abnormal growth. Lung cancer is of two types:
- Small cell lung cancer - This type of lung cancer begins in the middle of the lungs and spreads very quickly.
- Non small cell lung cancer - It is the most common type of lung cancer which is subdivided into three types - adenocarcinoma, squamous cell carcinoma, and large cell carcinoma. Adenocarcinomas are found in the outer part of the lungs, squamous cell carcinomas are found in the inner lining of the cells, and large cell carcinoma can be found in any part of the lungs.
Lung cancer is the most common type of cancer throughout the world, but its prevalence is extremely high in males. The primary reason to this is cigarette smoking. Cigarette smoking is one of the most common causes of lung cancer and millions of men throughout the world smokes. Cigarette consists of a large number of chemicals that cause damage to the tissues in the body. Over time, as the damage continues due to persistent cigarette smoking, the body fails to heal and as a result, it leads to the occurrence of lung cancer.
3. Colorectal cancer
Colorectal cancer is one of the leading causes of deaths from cancer and it is a common type of cancer for both men and women. When cancer begins in colon, it is known as colorectal cancer. Most often, colorectal cancer starts when there is a growth in the inner lining of colon and these growth is known as polyps. Polyps are of two types:
- Adenomatous polyps - These type of polyps sometimes changes into cancer. It is also known as precancerous condition.
- Hyperplastic polyps - These are the most common type of polyps which are generally non cancerous.
Colorectal cancer begins in mucosa, which is the innermost layer of the colon and can later spread to some or all other layers. Studies have reported that there are many different number of risk factor for colorectal cancer including age, family history, smoking, alcohol consumption, obesity, and diet. When colorectal cancer is diagnosed at an early stage, the survival rate is higher and it is estimated that most of the colorectal cancer cases are diagnosed at early stage. When colorectal cancer spreads outside the colon, the survival rate declines. Therefore, colorectal screening is recommended to people so that it can be diagnosed at early stage.
4. Bladder cancer
The bladder is a part of urinary system and is located near the pelvis, The bladder is a muscular sac that stores urine. Bladder cancer begins in the inner lining of the bladder. Primarily bladder cancer is of three types:
- Urothelial carcinoma - It is the most common type of bladder cancer which is also known as transitional cell carcinoma. It begins in the urothelial cells lining the walls of the bladder.
- Squamous cell carcinoma - It is the type of cancer that begins in the thin flat cells in the lining of the cells.
- Adenocarcinoma - It is estimated that 1% of all bladder cancer cases is of adenocarcinoma and it is a type of bladder cancer that begins in the glandular cells of the bladder.
Bladder cancer does not show many symptoms, some of the symptoms that an individual with bladder cancer may experience include changes in bowel movement, blood in the urine, and pain in one side of lower abdomen or back pain. There are many risk factors for bladder cancer such as cigarette smoking, exposure to carcinogenic chemicals, and diet. It is believed that most of the bladder cancer are superficial and their treatment can be relatively simple.
