8 Most Common But Deadliest Cancers (HEARTH FIRST)

While cancer is a scary subject to discuss, it is also imperative to be informed and aware of the occurrences and mortality rates concerning this disease. Here are 8 of the most common but deadliest forms of cancer.

1. Lung Cancer

2. Colorectal Cancer

Estimated to account for 221,200 cases in 2015 and 158,040 deaths, lung cancer is the most common and deadliest form of cancer according to the National Cancer Institute.

Non-small cell and small cell are the two distinct types of lung cancer and they’re individually identified based on how they appear under a microscope. Non-small cell is the most common.
While lung cancer can be caused by a variety of reasons, some even unknown, the bulk of lung cancer cases are due to tobacco smoking or secondhand inhalation of tobacco smoke. Most people who are diagnosed with lung cancer unfortunately succumb to the disease.

3. Breast Cancer

 Originating in the colon or rectum, colorectal cancer will claim an estimated 49,700 lives in 2015 out of 132,700 estimated new cases.
Growth formation within the inner wall of the colon or rectum is how the early stages of this type of cancer begin. The growth, known as a polyp, has the potential to become cancerous over a long period of time. It is not uncommon for multiple polyps to form in the same general area.
In terms of diagnosis and prevention, locating and removing polyps through a medical test known as a colonoscopy can greatly increase the survival rate for both men and women. Fecal occult blood tests also serve as a prominent way to test for, and potentially prevent, the onset of colorectal cancer. This information, including the aforementioned statistics, are courtesy of the National Cancer Institute.



Quite possibly the most notable form of cancer in terms of national discussion, breast cancer will claim an estimated 40,700 people (440 men) in 2015.
With a potential diagnosis rate of over 233,000 this year, breast cancer is the second most common cancer in women, with skin cancer being the most prominent. According to the National Cancer Institute, the most common type of breast cancer is ductal carcinoma.
In terms of evasiveness, breast cancer is most deadly when it metastasizes from the points of origin within the ducts or lobules. In terms of medical testing, a yearly mammogram is vital in respect to early detection and positive outcome.

4. Pancreatic Cancer

Arguably the most difficult type of cancer to diagnose, pancreatic cancer is alarmingly fatal. Per the National Cancer Institute, an estimated 48,960 people will be diagnosed in 2015 and 40,560 of those individuals will unfortunately succumb to the disease.
In terms of formation, the majority of pancreatic cancers originate in exocrine cells. The lack of hormone secretion within these tumors is the most significant reason why pancreatic cancer is essentially unable to be diagnosed at an early stage. While various treatments do exist, the five-year survival rate associated with pancreatic cancer is 6%.
 

5. Prostate Cancer

The most common form of cancer among men in the United States is prostate cancer. In respect to discussion and awareness, prostate cancer and breast cancer share a prominent standing in terms of global attention.
While the National Cancer Institute projects that 27,540 men will die from prostate cancer this year, historically speaking, based on statistics, prostate cancer is still the second deadliest cancer among men. In terms of racial comparison, African-American men are more likely to die from this disease than white men.
Often beginning with no symptoms, advanced prostate cancer typically becomes noticeable in the form of weak urine flow. However, this same symptom can also be caused by benign prostate ailments such as an enlarged prostate.
In terms of positive aspects, prostate cancer moves at a very slow pace. Early diagnosis, courtesy of routine physical exams, can dramatically improve survival rates compared to many other prominent forms of cancer noted within this list. Statistically speaking, an estimated 220,800 men will be diagnosed with prostate cancer this year.

6. Leukemia

Expected to claim over 24,000 lives this year, leukemia is a potentially fatal disease of the blood cells. Occurring in various forms, the type leukemia an individual has is based on the type of blood cell that has been compromised.
Additionally, leukemia is either acute or chronic in nature. Acute leukemia is defined as a rapidly growing cancer that can lead to death in a very short time. In fact, acute leukemia can be fatal not long after diagnosis. Chronic leukemia, on the other hand, grows at a rather slow pace.
In respect to outcome, the most notable determining factor, as noted above, lies in which blood cell has been compromised. Typically impacting older adults and children, leukemia is the most common cancer of individuals younger than 15 years of age. The National Cancer Institute estimates that 54,270 people will be diagnosed with some form of leukemia in 2015.

7. Lymphoma

Cancer that originates in the cells of the lymph system is known as lymphoma.
Serving as a major part of the immune system, the lymph system plays a critical role when it comes to protecting your body against disease and infection. While lymphoma is presented in two specific types, Hodgkin lymphoma and non-Hodgkin lymphoma, the latter, NHL, is one of the most common and deadliest forms of cancer.
While Hodgkin lymphoma is noted by the occurrence of abnormally large white blood cells in the lymph nodes called Reed-Sternberg cells, this type of lymphoma can usually be cured without major complications. However, NHL is far more complex and much more serious in nature. NHL can impact a host of cells and the disease can be quite aggressive.
Diffuse large B-cell lymphoma and follicular lymphoma are the most common types of NHL in adults. The National Cancer Institute projects that 71,850 lives will be compromised by NHL this year and roughly 20,000 lives will be lost to this disease.

8. Bladder Cancer

Rounding out the list in terms of estimated mortality statistics within the 2015 calendar year, the National Cancer Institute notes that bladder cancer is estimated to claim 16,000 lives this year and directly impact as many as 74,000.
Designed to store urine until it is evacuated out of the body, the bladder is a hollow organ. Cells within the bladder known as urothelial cells are the main victims of cell carcinoma, which is the most common type of bladder cancer. Other types of bladder cancer include squamous cells carcinoma and adenocarcinoma.
Long considered to be a major threat to tobacco smokers due to chemical exposure by the bladder, those who experience chronic bladder infections are also at risk. Passing blood during urination is considered the most common symptom of this disease.
Visual warning signs, which often occur early, can potentially lead to a successful outcome where this cancer is concerned.
