Get ready for a post answering some of the questions most frequently googled about cancer, focusing on statistics.
Which cancer is the most common?
Based on data from 2012, the three most common cancers in the world are lung, breast, and colorectal.
- 1,825,000 new cases of lung cancer were diagnosed worldwide in 2012
- 1,677,000 new cases of breast cancer worldwide that year
- 1,361,000 newly diagnosed cases of colorectal cancer globally in 2012
Inside the U.S. alone, things switch up a little with the three most common in 2013 being breast cancer, lung cancer, and prostate cancer from highest to lowest.
This changes yet again if you limit the geographic area to just Utah (where VLCM Foundation is). The three most commonly diagnosed cancers in 2014 were breast cancer, prostate cancer, and melanoma--again, from highest to lowest.
Which cancer is the most rare?
In the U.S., some of the rarest forms of cancer occur in parts of the body most of us didn't know we have.
- Cancer of the trachea and mediastinum - the trachea is the the airway through which air travels to the lungs and the mediastinum is a membrane between the lungs
- Kaposi sarcoma - cancer that develops in the cells which line blood vessels and the lymphatic system
- Cancer of the retroperitoneum - cancer that occurs in a part of the abdomen which is sectioned off from the rest by a membrane
Which cancer is the most curable?
'Cure' is perhaps still a strong word to use with cancer. The disease can become stable for long periods (meaning it's still there but isn't changing) or go into complete remission if all tumors that can be measured or tested for are completely gone for at least one month. Complete remission is not necessarily a cure; cancer could reoccur. There's still some debate about using that word.
However, some cancers are definitely more treatable or survivable. Researchers quantify this with a number called a 5-year survival rate. It's the percentage of patients who are alive 5 years after the date they were diagnosed or started treatment.
Some of the cancers with the highest 5-year survival rates in the U.S. are:
- Prostate cancer (98.2% live 5 years)
- Thyroid cancer (98.1% overall live 5 years - 95.6% for males, and 98.8% for females)
- Cancer of the testis (95.3% survive 5 years)
- Melanoma (91.8% overall life 5 years - 89.9% for males, 94.2% for females)
- Breast cancer (89.6% overall survive 5 years - 83.3% for males, 89.7% for females)
Which cancer causes the most deaths?
Some of the cancers with the lowest 5-year survival rates in the U.S. are:
- Pancreatic cancer (8.5% overall survive 5 years - 8.8% for males, 8.3% for females)
- Mesothelioma (9.4% overall live 5 years - 7.0% for males, 16.6% for females)
- Liver cancer (17.7% overall survive 5 years - 17.5% for males, 18.4% for females)
- Lung cancer (18.6% overall live 5 years - 15.5% for males, 22.0% for females)
- Esophageal cancer (19.2% overall survive 5 years - 18.9% for males, 20.0% for females)
Which cancer kills the fastest?
Two types of cancer are infamous for appearing to kill quickly: pancreas and lung. The reason is because the cancers are often diagnosed at very late stages of the disease, at which point little can be done to treat them.
