Cancer Causing Agents - Carcinogens (cont.)
Because of the importance of cancer and agents which may cause it, we here provide some of the highlights of this Report.
Listing in the Report
A listing in the Report does not by itself establish that a substance presents a cancer risk to an individual in daily life.
The Report also does not try to balance the potential benefits of exposures to certain carcinogenic substances in special situations. For example, a number of drugs used to treat cancer have been shown to increase the occurrence of secondary cancers. In these instances, the benefits of exposure to the drugs for treatment or prevention of a specific disease have been determined by the Food & Drug Administration (FDA) to outweigh the additional cancer risks associated with their use. People should not make decisions concerning the use of a given drug, or any other listed agent, based solely on the information contained in the Report. Decisions of this type should be made only after consulting with a physician or other appropriate specialist about both risks and benefits.
"Known" versus "Reasonably Anticipated" To Be a Carcinogen
An agent or exposure can be listed in the Report as "known to be a human carcinogen" or as "reasonably anticipated to be a human carcinogen."
The "known" category is reserved for those substances for which there is sufficient evidence of carcinogenicity from studies in humans that indicates a cause and effect relationship between the exposure and human cancer.
The "reasonably anticipated" category includes those substances for which there is limited evidence of carcinogenicity in humans and/or sufficient evidence of carcinogenicity in experimental animals.
Six substances have been added to the "known" category:
- Allergic Skin Disorders
- Bacterial Skin Diseases
- Bites and Infestations
- Diseases of Pigment
- Fungal Skin Diseases
- Medical Anatomy and Illustrations
- Noncancerous, Precancerous & Cancerous Tumors
- Oral Health Conditions
- Papules, Scales, Plaques and Eruptions
- Scalp, Hair and Nails
- Sexually Transmitted Diseases (STDs)
- Vascular, Lymphatic and Systemic Conditions
- Viral Skin Diseases
- Additional Skin Conditions
