Antitumour refers to any treatment or medication that has the ability to hinder or reduce the growth of tumours. There are several synonyms for antitumour, such as anticancer, antineoplastic, antiproliferative, and antineoplastic agent. These terms are often used interchangeably in medical literature and discussions. The goal of these treatments is to target cancerous cells specifically and prevent them from dividing and multiplying, thereby slowing down or stopping the growth of tumours. Antitumour therapies can be an essential component of cancer management, and they can be used in conjunction with other treatments such as chemotherapy and radiation therapy. By identifying effective antitumour agents, researchers and clinicians can work towards improving cancer outcomes for patients.
