Carcinoma

Definition

• A carcinoma is a malignant (cancerous) growth that arises from the epithelium (the covering of internal and external surfaces of the body, including the lining of vessels and other small cavities). This includes the skin and lining of the organs such as breast, prostate, lung, stomach or bowel.

Additional Info

Carcinomas tend to spread (a process called metastasis) through the blood vessels, lymph channels or spinal fluid to other organs such as the bone, liver, lung or the brain. See the last two links under Further Reading for more information.

According to the American Cancer Society, at least 80% of all cancers are carcinomas.

MSDS Relevance

"Carcinomas" usually appears on an MSDS as a health effect caused by chronic (long-term) exposure to a carcinogen (cancer-causing substance). The MSDS may specifically mention studies that have shown this effect in animals and/or humans. Use extreme caution when working with carcinogenic (or potentially carcinogenic) materials in the workplace. Be sure to use all proper personal protective equipment (PPE) and to minimize your exposure. Find alternative procedures or materials if possible. Proper engineering controls and adminstrative controls are definitely required when working with carcinogens or potential carcinogens!

Ensure OSHA compliance with training materials and supplies from Safety Emporium.
