Cancer is a lethal disease, which is causing an increase in mortality rate. It is becoming the second major cause of deaths. When cells lost control over its rate of division, it becomes abnormal and starts to proliferate. There are many causes of abnormal cell formation like inherited effects and environmental issues. We can decrease the mortality rate by decreasing or removing the causative agents of cancer. Environmental causes can be decreased by human activities that will not cause pollution. There are many types of cancer. Some types are common and are not dangerous. Some are rare and most dangerous. These types lead to death.
Some lethal types of cancer are as follow:
- Lip cancer
- Skin cancer
- Breast cancer
- Prostate cancer
- Bladder cancer
- Testicular cancer
- Ocular cancer
- Thyroid cancer
Skin cancer is the development and uncontrollable division of cells in the skin.
Symptoms of skin cancer
The painless swell area on the skin that may appear shiny and show small blood vessels over it.
Basal cell skin cancer
Squamous cell skin cancer
Basal cell and squamous cell skin cancer are two nonmelanoma skin cancers. The first type is slow growing and less spreading. The second type spreads to other parts and causes death. Melanoma is the most dangerous type of skin cancer.
Risk factors for skin cancer include ultraviolet radiations, poor immune system, and light skin.
Treatments include surgery, fluorouracil, and radiation therapy.
It is the growth of abnormal cells in the area of the breast. It may remain confined to breast or may spread to other parts of the body.
- Change in breast shape
- Lump or swelling in the breast
- Dimpling of the skin
- Inverted nipple
- Red patches on the skin
- Discharge of fluid or blood from nipples
- Hotness of breast
Causes of breast cancer
There are many causes of breast cancer. Some important causes are obesity, alcohol, lack of physical activity, hormone replacement therapy, ionizing radiation, older age and family history.
Surgery is the removal of the whole breast or the removal of only affected part of the breast.
It is the growth of abnormal cells in the area of the prostate. The prostate is a gland of the male reproductive system.
Its symptoms include no or difficulty in urination, pain in the pelvis, blood in the urine, pain in the back and pain during urination.
Its risk factors include old age factors and family genetic history.
Treatment of prostate cancer includes surgery, hormone therapy, radiation therapy and chemotherapy.
It is the growth of abnormal cells in the testicles.
Pain and swelling in the scrotum and lump in testicles.
Its types include lymphoma, sex cord-stromal tumors and germ cell tumor.
Family genetic history and undescended testicles.
Radiation therapy, surgery, chemotherapy, hormonal therapy, and radiation therapy are important treatments.
It is the growth of abnormal cells in the thyroid gland. The thyroid gland is an important gland, which controls the rate of metabolism. It is present in the neck below the pharynx.
Its symptoms include a lump or swelling of the thyroid gland in the neck.
Exposure to rays and deficiency of iodine in the diet.
Its treatments are radiation therapy, surgery, chemotherapy, targeted therapy, and thyroid hormone therapy.
