When pancreatic cancer is discovered, it is typically too late in the progression trail to treat the disease with any success. Although various treatments for pancreatic cancer do exist, the five-year survival rate is, unfortunately, less than six per cent.

Prostate Cancer

The most common form of cancer among men who reside in the United States — prostate cancer tragically extinguished the lives of roughly 28,000 men in 2015. Plaguing the African American community, black men are more likely to succumb to prostate cancer than white men.

Often commencing with no symptoms, prostate cancer typically becomes problematic only during its advanced stages, where a weak urine flow becomes quite noticeable. The only way to detect this form of cancer is through a prostate exam performed by a physician.


Claiming the lives of 24,000 people a year, leukemia is a potentially fatal disease involving blood cells. The type of leukemia a person is afflicted with is based on which blood cells has been compromised.

Typically afflicting older adults and children, leukemia is statistically noted as the most common cancer of those under 15 years. Per the National Cancer Institute, an estimated 54,000 people were diagnosed with some form of leukemia in 2015.


Cancer that forms within the lymphatic system cells is known as lymphoma. Being part of your body’s immune, the lymphatic system serves to shield the body against various types of disease and infection.

Presented in two very distinguishable types, Hodgkin and Non-Hodgkin, lymphoma can produce a very mixed outcome depending on the diagnosis.

Non-Hodgkin lymphoma — also known as NHL, is the most common and, unfortunately, the most deadly. While Hodgkin lymphoma is quite serious, Who can usually cure this type of lymphoma without major complications?

Bladder Cancer

The National Cancer Institute has noted that bladder cancer claimed an estimated 16,000 lives and negatively impacted as many as 74,000 in 2015. The urothelial cells are the primary cells compromised by what is known as cell carcinoma. Squamous cell carcinoma and adenocarcinoma are the main types of bladder cancer.

Historically considered a major threat to those who smoke tobacco, bladder cancer is largely due to chemical exposure that directly impacts the bladder itself. Additionally, individuals plagued by bladder infections are also at risk due to the chemical agents that can form within the organ. A urine stream consisting of blood is noted as the most common sign.

Kidney Cancer

While acts such as smoking and taking specific pain medications for many years can increase the odds for development, kidney cancer can impact anyone regardless of age or gender.

Endometrial Cancer

Endometrial cancer took the lives of an estimated 10,170 people this year out of a diagnosis pool of 54,870. In the starting region for most uterine cancers, endometrial cancers can form in cells that produce their mucus and other fluids.
