Tc-99
Iodine-131 (I-131) is a radioisotope commonly used in medicine for treating thyroid disorders, particularly hyperthyroidism and thyroid cancer. It emits beta and gamma radiation that can destroy the overactive thyroid tissue or thyroid cancer cells.

Technetium-99m (Tc-99m) is commonly used as a radioisotope to detect blood clots in the body. It is often used in a procedure called a venous scan or a lung scan, where it helps visualize blood flow and identify blockages or clots in the veins or lungs. The radioisotope emits gamma rays, which can be detected by a gamma camera, allowing for imaging of the affected areas.
The Papanicolou test is used to detect possible precancerous and cancerous lesions that need further evaluation. It is not a diagnostic test, but is a screening test. Most commonly, we think of pap smears as detecting cervical cancer, but they may also be used to detect vaginal or anal cancer.
A cervical smear, also known as a Pap smear, is a screening test used to detect abnormalities in the cells of the cervix that could potentially lead to cervical cancer. During the procedure, cells are collected from the cervix and examined under a microscope for any signs of pre-cancerous or cancerous changes. It is a routine test recommended for women to help prevent cervical cancer.
PAP Smear
A cytology laboratory test involves examining cells under a microscope to detect abnormalities, infections, or cancer. It is commonly used to diagnose diseases such as cervical cancer, lung cancer, and leukemia by analyzing cells obtained from various body fluids or tissue samples.
No, these devices do not cause cancer or they would not be used in hospitals. They can detect cancer and are also used on pregnancy so they do not cause cancer!
One radioisotope commonly used to attach to red blood cells is technetium-99m (Tc-99m), which is used in nuclear medicine imaging procedures such as a technetium-99m red blood cell scan. It is injected into the bloodstream and binds to red blood cells to help visualize blood flow and detect abnormalities.
Nanotechnology can use to develop bio indicators a type of molecules which will attached to infected cells, they also can be detected from scanning. let say nanotechnology can be used to develop a dye to indicate cancer cells and when a patient given that, the dye molecules will selectively attached to the cancer cells and the dye concentration will increase around the cancer. And once the scanning is done dye can be identified hence the cancer.
A gynecologist can perform a Pap smear to find any abnormal cells. You will need to make an appointment at an Obgyn for this.
