Introduction

"Taking tissue" usually refers to sampling. After a biopsy, immunohistochemistry generally does not require additional sampling. A biopsy involves removing tissue samples from a patient's body for pathological examination. Immunohistochemistry then applies staining and visualization techniques to these tissue samples. During the biopsy procedure, doctors typically collect sufficient tissue, which is adequate for immunohistochemical testing. Therefore, additional sampling is usually unnecessary.

Biopsy usually refers to sampling, and additional sampling is generally not required for immunohistochemical testing after a biopsy. Detailed explanation is as follows:

A biopsy involves removing tissue samples from a patient's body for pathological examination. Immunohistochemistry detects abnormal proteins, carbohydrates, or other substances by staining and visualizing the tissue samples. During a biopsy, doctors typically collect sufficient tissue, which is adequate for subsequent immunohistochemical testing. Therefore, re-sampling is usually unnecessary.

In addition, biopsy specimens undergo special processing during preservation to ensure their quality and integrity, facilitating accurate immunohistochemical analysis. After the procedure, it is important to rest appropriately and properly care for the wound to prevent infection.

If any discomfort occurs or test results indicate abnormalities, it is recommended to seek timely medical evaluation and treatment at a hospital.

Can a PET-CT scan detect skin cancer?

If only the primary tumor on the skin surface needs to be diagnosed, PET-CT is usually not the first choice. Primary lesions of skin cancer often present as superficial abnormalities such as masses or plaques, which can be accurately diagnosed through visual inspection, dermoscopy, and pathological biopsy. PET-CT is not only more costly, but also less precise than specialized examinations in detecting small, superficial lesions. Indiscriminate use may lead to unnecessary resource waste.
