What is cancer?
Is it a disease or an illness?
What causes it?
What is the cure?
In a new study, researchers from Johns Hopkins University and the University of California at Berkeley looked at cancer statistics for the U.S. from the 1900s through 2010.
They found that between one-third and two-thirds of people diagnosed with cancer had never had a previous diagnosis, and many were diagnosed without knowing what their condition was.
In addition, some cancers are more prevalent in certain regions of the country.
“People who are diagnosed with the disease do not have any idea what their disease is or whether it will make them sick or not,” said study co-author Thomas L. Cavanaugh, M.D., Ph.
D. The study is published online today (Jan. 16) in the journal JAMA Internal Medicine.
What they found is that, despite the fact that cancer is an incredibly complex disease, most people are diagnosed and treated based on a few basic facts: What is in your body?
What you eat and drink?
What makes you sick?
What kind of treatments work best for you?
“We wanted to see how well a person’s health was improved by the fact they had not been diagnosed with a previous cancer,” said Lacy Cavanaugh of Johns Hopkins.
“The best way to do that is to give them the information they need.”
The Johns Hopkins study included more than 1.5 million people who were diagnosed with at least one form of cancer between 1900 and 2010.
The data showed that about 90 percent of people with cancer were diagnosed within five years of their diagnosis.
Some of the differences in the numbers of people who developed cancer and who did not were not statistically significant, and most were between 5 and 20 years apart.
The most common cancer diagnoses for people with no previous history of cancer were breast cancer (13.7 percent), thyroid cancer (12.4 percent), colon cancer (11.3 percent), ovarian cancer (10.6 percent), prostate cancer (9.7 and 10.6, respectively), and lung cancer (8.6 and 8.4, respectively).
Other cancers were found to be more common among people with a history of previous cancer: melanoma (4.6 per 10,000), pancreatic cancer (3.4 per 10,” and lung/bronchial cancer (2.8), respectively).
“They may be unaware of any known treatments or may not be able to find a health care provider that can discuss it with them. “
It’s important to note that people who have cancer may not know what it is and are not likely to know how to prevent it,” said lead author and Johns Hopkins professor of medicine, Dr. Lacy L. L. Kavanaugh, M., Ph., in a statement.
For example, if the person had family history or other health issues, such as being diagnosed with diabetes, that could make their diagnosis more likely to be inaccurate. “
That’s why we needed to look at these populations, and to do so, we looked at the health records of a very large number of people from different ethnic and racial groups, so that we could see whether or not the person’s family history of the disease, their geographic location, and their socio-economic status were all factors in the diagnosis.”
For example, if the person had family history or other health issues, such as being diagnosed with diabetes, that could make their diagnosis more likely to be inaccurate.
“This study shows that cancer diagnoses are not an anomaly,” said Dr. Caughlin.
“Most people have them.”
Findings suggest that the incidence of cancer in the U: More common than at any other time in human history.
Nearly one-fifth of all cancers were diagnosed between 1900 to 2010.
