Cytotechnologists examine cells from other sites, including lymph nodes, bladder and lungs. Cytotechnology professionals often work with a pathologist to determine whether cells show signs of precancerous lesions, infections and other malignancies.

Pathologists are physicians who diagnose presence and stage of diseases using laboratory techniques and patient specimens. They study the nature, cause, and development of diseases. They may also perform autopsies.

Nuclear medicine technologists assist physicians and work directly with patients to explain nuclear medicine procedures. They also administer and oversee nuclear medicine and radioactive procedures and substances.
