Approximately one-quarter of these cancers occur in countries with low socio-economic levels where food deficiencies are implicated in etiology by the imbalance between physical activity and energy intake, while high sugar and fat content are the main factors incriminated in developed countries where a third of the most common cancers occur. The relationship between diet and cancer risk is complex.
Papillomavirus verrues of Texas M. Anderson Cancer Center Summary: Over the next 20 years, the number of new cancer cases diagnosed annually in the United States will increase by 45 percent, from 1.
Anderson Cancer Center.
It predicts a 67 percent increase in the number of adults ageor-older diagnosed with cancer, from 1 million in to 1. In non-white individuals over the same year span, the incidence is expected to increase by percent, fromtoAccording to Ben Smith, M.
Anderson's Department of Radiation Oncology, the study underscores cancer's growing stress on the U. To conduct their research, Smith and his team accessed the United States Census Bureau statistics, updated in to project population growth throughand the National Cancer Institute's Surveillance, Epidemiology and End Results SEER registry, the premier population-based cancer registry representing 26 percent of the country's population.
Cancer incidence rates were calculated by multiplying the age, sex, race and origin-specific population projections by the age, sex, race and origin-specific cancer incidence rates. The total number of cancer cases will increase by 45 percent from 1. With respect to race, a percent increase in cancer is expected for minorities.
The rates of cancer in blacks, American Indian-Alaska Native, multi-racial, Asian-Pacific Islanders and Hispanics will increase by 64 percent, 76 percent, percent, percent and percent, respectively. Regarding disease-specific findings, Smith and his team found that the leading cancer sites are expected to remain constant - breast, prostate, colon and lung.
However, cancer sites with the greatest increase in incidence expected are: stomach 67 percent ; liver 59 percent ; gastric cancer prevalence 57 percent ; pancreas 55 percent ; and bladder 54 percent.
Given these statistics, the role of screening and prevention strategies papillomavirus remede all the more vital and should be strongly encouraged, said Smith.
In the study, Smith and his team site: vaccinations for hepatitis B and HPV; the chemoprevention agents tamoxifen and raloxifene; interventions for tobacco and alcohol; and removal of pre-malignant lesions, such as colon polyps. These findings also highlight two issues that must be addressed simultaneously: clinical trial participation and the increasing cost of cancer care.
Historically, both older adults and minorities have been under-represented in such studies, and, therefore, vulnerable to sub-optimal cancer treatment. Simultaneously, over the past decade in particular, the cost of cancer care is growing at a rate that's not sustainable.
These are two issues that oncologists need to be much more concerned about and attuned to.
For example, according to a workforce assessment by American Society for Clinical Oncology ASCOthe shortage of medical oncologists will impact the health care system by Smith said ASCO and other professional medical organizations beyond oncology are aware of the problem, and are actively engaged in efforts to try and grow the number of physicians, as well as encourage the careers of nurse practitioners and physician assistants who are part of the continuum of care, to best accommodate the increase in demand gastric cancer prevalence.
There will not be one solution to this problem, but many different issues that need to be addressed to prepare for these changes," said Smith.
