Abstract: Cancer is one of life's most difficult difficulties and a severe health risk everywhere. Except for haematological
malignancies, it is characterized by unchecked cell growth and a lack of cell death, which results
in an aberrant tissue mass or tumour. Vascularization promotes tumor growth, which eventually aids metastasis
and migration to other parts of the body, ultimately resulting in death. The genetic material of the cells is
harmed or mutated by environmental or inherited influences, which results in cancer. Presently, anti-neoplastic
medications (chemotherapy, hormone, and biological therapies) are the treatment of choice for metastatic cancers,
whilst surgery and radiotherapy are the mainstays for local and non-metastatic tumors. Regrettably, chemotherapy
disturbs healthy cells with rapid proliferation, such as those in the gastrointestinal tract and hair follicles,
leading to the typical side effects of chemotherapy. Finding new, efficient, targeted therapies based on
modifications in the molecular biology of tumor cells is essential because current chemotherapeutic medications
are harmful and can cause the development of multidrug resistance. These new targeted therapies, which
are gaining popularity as demonstrated by the FDA-approved targeted cancer drugs in recent years, enter
molecules directly into tumor cells, diminishing the adverse reactions. A form of cancer treatment known as
targeted therapy goes after the proteins that regulate how cancer cells proliferate, divide, and disseminate.
Most patients with specific cancers, such as chronic myelogenous leukemia (commonly known as CML), will
have a target for a particular medicine, allowing them to be treated with that drug. Nonetheless, the tumor
must typically be examined to determine whether it includes drug targets.
