Revolution in the treatment of cancer: a new drug shows outstanding results

I. Prerequisites and context of the development of cancer

1. Global burden of cancer: epidemiological data and trends.

   • Cancer is one of the leading causes of mortality around the world.
   • Millions of new cancer cases are diagnosed annually, and this figure is expected to grow.
   • Factors affecting the incidence of cancer: aging of the population, lifestyle (smoking, nutrition, physical activity), environmental impact (pollution, radiation), genetic predisposition.
   • Statistics of incidence and mortality in various types of cancer (lung cancer, breast cancer, colon cancer, prostate cancer and others).
   • The uneven distribution of the incidence of cancer in different regions of the world related to socio-economic factors and the availability of medical care.

2. Modern methods of cancer treatment: achievements and restrictions.

   • Surgical intervention: removal of a tumor is often the first step in the treatment of localized forms of cancer. Restrictions: it is not always possible to completely remove the tumor, the risk of relapse, the side effects of surgical intervention.
   • Radiation therapy: the use of ionizing radiation to destroy cancer cells. Restrictions: damage to healthy tissues, side effects (fatigue, skin reactions, reduction of appetite).
   • Chemotherapy: the use of drugs to destroy cancer cells. Restrictions: non -specific effect (damage to healthy cells), side effects (nausea, vomiting, hair loss, reduction of immunity), development of resistance to drugs.
   • Targeted therapy: effect on specific molecular targets in cancer cells. Advantages: more specific effect, less side effects than chemotherapy. Restrictions: Efficiency depends on the presence of a specific target, the development of resistance.
   • Immunotherapy: activation of the immune system to combat cancer. Advantages: can lead to prolonged control over the disease, less side effects than chemotherapy. Restrictions: Efficiency depends on the type of cancer and individual characteristics of the patient, the possibility of developing autoimmune reactions.
   • Combined therapy: the use of several treatment methods simultaneously or consistently. Purpose: to increase the effectiveness of treatment and reduce the risk of resistance.
