Generally, Cancer is known to be a serious terminal illness with the chances of surviving it being slim. It is also incurable and if you don’t catch it on time it can become very deadly.
Some cancers, when caught early, can be managed, with the carrier living long after treatment. But others are deadly, incurable and have killed more people than the other milder forms of cancer.
These are 5 of them.
1. Lung Cancer
Smoking is the most common cause of lung cancer. Based on microscopic examination, lung cancer is divided into 2 types, small-cell lung cancer, and non-small cell lung cancer.
Depending on the type and stage of lung cancer, treatment can include surgery, chemotherapy, and radiotherapy.
Sadly, most people with advanced lung cancer will eventually die of the disease.
2. Colorectal Cancer
Initially, colorectal cancer has few or no symptoms. If it is caught early, colorectal cancer is treatable with encouraging 5-year survival rates. For example, survival rates for some people with early-stage colorectal cancer are around 90 percent.
In order to survive colorectal cancer, screening like colonoscopy is imperative. Unfortunately, five-year survival rates for advanced colorectal cancer are much lower.
Depending on the stage and spread of colorectal cancer, treatment can include surgery, radiotherapy, chemotherapy or embolization.
3. Breast Cancer
Breast cancer is caused by the malignant growth of cells lining the lobules or ducts of the breast. About one percent of all breast cancers affect men.
Breast cancer arises from a clone or a single transformed cell. Typically, it takes time for such clonal cells to become fully malignant and invade and metastasize (spread to other parts of the body).
The treatment of breast cancer can get quite complicated and is based on numerous factors. Broadly, breast cancer treatment can be characterized as extensive mastectomy or breast-conserving lumpectomy.
In addition to local surgical therapy, adjuvant or systemic therapy is also given to treat people with breast cancer.
Such adjuvant therapy can include chemotherapy or hormone therapy. Fortunately, with improvements in diagnostic and treatment capabilities, more people who are diagnosed with breast cancer survive.
4. Pancreatic Cancer
Pancreatic cancer is one of the most aggressive cancers in existence. It kills quickly and besets the patient with multiple painful and dangerous symptoms including stomach pain, biliary obstruction, bleeding, ascites and more.
Despite research into the subject, there are no good screening options or treatments for people pancreatic cancer.
5. Prostate Cancer
The prostate is a gland found in men only. It sits in the middle of the lower pelvis nestled among the rectum and bladder. The prostate makes the seminal fluid which nourishes sperm.
Prostate cancer arises from glandular cells and is thus an adenocarcinoma. This disease usually affects older men and is most common among African Americans and those with a family history of the disease.
Most prostate cancers are slow growing, and people with asymptomatic prostate cancer are usually observed with no further treatment. In fact, many people with prostate cancer die of unrelated causes like a heart attack or stroke.
Treatment of prostate cancer includes surgical removal prostatectomy, external beam radiation therapy radiotherapy, and brachytherapy. Brachytherapy is a procedure in which radioactive iodine is implanted into the prostate.
