Top 5 Incurable Diseases and Tips For Prevention

With all the advancements in medical research, there are still some diseases that cannot be cured. Not all incurable diseases are fatal. Common cold, for instance, is the most common among diseases that cannot be cured. It is also the least dangerous. This article is about the top five diseases with no known cure.

1. The Common Cold

The common cold is an acute viral infection that affects the upper respiratory tract. Sometimes it affects the lower structures too and can cause ear and eye infections. The common cold is caused by more than 100 agents, the most important among them being the Rhinoviruses. Other pathogens that cause common cold include parainfluenza, influenza, respiratory syncytial viruses, and reoviruses. The common cold is a highly contagious disease. It is not caused from exposure to a cold environment. The cause is exposure to infected people.

2. Cancer

The term cancer refers to a group of more than 100 distinct diseases. Every form of cancer is characterized by the uncontrolled growth of abnormal cells in the body. Cancer affects a lot of people and is a major cause of illness and death throughout the world.

Cancer isn’t totally incurable. It isn’t totally curable either. Since the 20th century there have been several advancements in cancer treatment in the form of selective surgery, radiation therapy and chemotherapy. Such advances have brought about a decrease in the number of cancer deaths. Cancer is a considered a lifestyle disease. Unhealthy lifestyles including smoking and exposure to environmental pollutants can cause cancer. Genetic factors too increase a person’s risk of getting cancer.

3. Asthma

Asthma is a chronic disorder affecting the lungs. It causes the airways to become constricted leading to episodes of breathlessness, coughing, wheezing and chest tightness. The severity of the symptoms can range from mild to life-threatening. Asthma is triggered by a variety of factors including dust mites, air pollution, pollen, animal dander, cigarette smoke, certain medications, cold weather conditions and exercise. Stress can worsen symptoms. Almost half of all asthma patients are children younger than 10 years of age. Childhood asthma is often caused by an inherited susceptibility to certain allergens. In adults, viral infections, exercise and aspirin can cause asthma. Asthma is an incurable disease. However, the severity of the symptoms can be lessened with the help of certain medications and changes in lifestyle.


AIDS is a disease of the immune system. It is caused by the human immunodeficiency virus (HIV). AIDS is not a disease in itself. It is actually a condition where the body’s defense system becomes compromised leaving an individual vulnerable to a variety of other infections that eventually lead to death. The factors that lead to an HIV infection include multiple sexual partners and intravenous drug use. Some 20 million people have died of AIDS since 1981. There are no cures yet. But with advanced retroviral drugs, it is possible to extend lifespan.

5. Diabetes

Diabetes is a metabolic disorder. A person develops diabetes when his body fails to produce insulin required to maintain proper blood sugar levels. There are two types of diabetes: Type I and Type II. The Type I diabetes usually develops during childhood. Patients suffering from Type I diabetes require daily insulin injections because their body can’t produce the hormone. The Type II diabetes usually develops in adulthood. Various studies have linked it to genetics and obesity. Type II diabetic patients can control blood sugar levels through changes in diet and exercise. They can also take insulin injections or oral medications.
