The American Cancer Society offers programs and services to help you during and after cancer treatment. Below are some of the resources we provide. We can also help you find other free or low-cost resources available.
At the American Cancer Society, we have a vision to end cancer as we know it, for everyone. We're improving the lives of cancer patients and their families through advocacy, research, and patient support to ensure that everyone has an opportunity to prevent, detect, treat, and survive cancer.
Cancer is a complex group of diseases with many possible causes. In this section you can learn more about the known and possible causes of cancer, as well as general information about carcinogens and how genetics play a role in cancer.
Some types of cancer run in certain families, but most cancers are not clearly linked to the genes we inherit from our parents. Learn about the complex links between genes and cancer, as well as genetic testing and how it is used.
Medical tests and treatments can be an important part of getting and staying healthy. But some types of tests and treatments may actually increase a person's risk of developing cancer. Get the facts about possible links between certain medical procedures and cancer.

Life on Earth depends on energy coming from the Sun. About half the light energy reaching Earth's atmosphere passes through the air and clouds to the surface, where it is absorbed and radiated in the form of infrared heat. About 90% of this heat is then absorbed by greenhouse gases and re-radiated, slowing heat loss to space.
Over the last century, burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO2). This increase happens because the coal or oil burning process combines carbon with oxygen in the air to make CO2. To a lesser extent, clearing of land for agriculture, industry, and other human activities has increased concentrations of greenhouse gases.
The industrial activities that our modern civilization depends upon have raised atmospheric carbon dioxide levels by nearly 50% since 1750. This increase is due to human activities, because scientists can see a distinctive isotopic fingerprint in the atmosphere.
In its Sixth Assessment Report, the Intergovernmental Panel on Climate Change, composed of scientific experts from countries all over the world, concluded that it is unequivocal that the increase of CO2, methane, and nitrous oxide in the atmosphere over the industrial era is the result of human activities and that human influence is the principal driver of many changes observed across the atmosphere, ocean, cryosphere and biosphere.
Scientists use a metric called Total Solar Irradiance (TSI) to measure the changes in energy the Earth receives from the Sun. TSI incorporates the 11-year solar cycle and solar flares/storms from the Sun's surface.
The Underlying Cause of Death database contains mortality and population counts for all U.S. counties. Data are based on death certificates for U.S. residents. Each death certificate identifies a single underlying cause of death and demographic data. The number of deaths, crude death rates or age-adjusted death rates, and 95% confidence intervals and standard errors for death rates can be obtained by place of residence (total U.S., region, state and county), age group (single-year-of age, 5-year age groups, 10-year age groups and infant age groups),race, Hispanic ethnicity, gender, year, cause-of-death (4-digit ICD-10 code or group of codes), injury intent and injury mechanism, drug/alcohol induced causes and urbanization categories.Data are also available for place of death, month and week day of death, and whether an autopsy was performed.
The Public Health Service Act (42 U.S.C. 242m(d)) provides that the data collected by the National Center for Health Statistics (NCHS) may be used only for the purpose for which they were obtained; any effort to determine the identity of any reported cases, or to use the information for any purpose other than for health statistical reporting and analysis, is against the law. Therefore users will: Use these data for health statistical reporting and analysis only. For sub-national geography, do not present or publish death counts of 9 or fewer ordeath rates based on counts of nine or fewer (in figures, graphs, maps, tables, etc.). Make no attempt to learn the identity of any person or establishment included in these data. Make no disclosure or other use of the identity of any person or establishment discovered inadvertently and advise the NCHS Confidentiality Officer of any such discovery.

The Multiple Cause of Death data available on CDC WONDER are county-level national mortality and population data. Data are based on death certificates for U.S. residents. Each death certificate contains a single underlying cause of death, up to twenty additional multiple causes, and demographic data. The number of deaths, crude death rates and age-adjusted death rates can be obtained by place of residence (United States national, state, and county), age group, race, Hispanic ethnicity, gender, year and month of death, weekday of death, place of death, autopsy status, and underlying and multiple cause of death (4-digit ICD-10 codes, 113 selected causes of death, 130 selected causes of death for infants, injury causes, or drug / alcohol induced causes of death). Two archive datasets offer subsets of these data.For more information, refer toMultiple Cause of Death data description.

HPV infection is common: Nearly all sexually active people are infected with HPV within months to a few years of becoming sexually active. Around half of these infections are with a high-risk HPV type.
High-risk HPV infections that persist can cause cancer: Sometimes HPV infections are not successfully controlled by your immune system. When a high-risk HPV infection persists for many years, it can lead to cell changes that, if untreated, may get worse over time and become cancer.HPV vaccination can prevent cancer: HPV vaccines can prevent infection with disease-causing HPV types, preventing many HPV-related cancers and cases of genital warts.
Long-lasting infections with high-risk HPVs can cause cancer in parts of the body where HPV infects cells, such as in the cervix, oropharynx (the part of the throat at the back of the mouth, behind the oral cavity that also includes the back third of the tongue, the soft palate, the side and back walls of the throat, and the tonsils), anus, penis, vagina, and vulva.
HPV infects the squamous cells that line the inner surfaces of these organs. For this reason, most HPV-related cancers are a type of cancer called squamous cell carcinoma. Some cervical cancers come from HPV infection of gland cells in the cervix and are called adenocarcinomas.
In the United States, high-risk HPVs cause 3% of all cancers in women and 2% of all cancers in men. Each year, there are about 45,000 new cases of cancer in parts of the body where HPV is often found, and HPV is estimated to cause about 36,000 of these, according to the Centers for Disease Control (CDC).
Worldwide, the burden of HPV-related cancers is much greater. High-risk HPVs cause about 5% of all cancers worldwide, with an estimated 570,000 women and 60,000 men getting an HPV-related cancer each year. Cervical cancer is among the most common cancers and a leading cause of cancer-related deaths in low- and middle-income countries, where screening tests and treatment of early cervical cell changes are not readily available. 59ce067264
