Benign rhabdomyosarcoma cell activity means that the rhabdomyosarcoma cells are active, suggesting increased hormone levels in the body, which may lead to further deterioration of the benign cells. Benign rhabdomyosarcoma cells are active, meaning that benign rhabdomyosarcoma cells differentiate faster than normal rhabdomyosarcoma cells, suggesting that the hormone level in the body has increased, but no obvious malignant lesions or rhabdomyosarcoma cells with tendency to malignant lesions have been observed so far. When encountering benign leiomyosarcoma cells active in clinic, it is necessary to follow up and observe regularly, review the growth rate of leiomyosarcoma cells, and intervene as soon as possible if the growth is rapid in a short period of time, or if there is a tendency of degeneration or malignant change. Therefore, patients with active benign leiomyosarcoma cells should be examined under the guidance of a doctor to clarify the cause, and consult a doctor as early as possible for regular review.
