Final answer:
Irreversible diseases cannot be completely cured with medication and surgery, but treatment can help manage symptoms and improve quality of life. These include chronic conditions such as Crohn's disease and certain autoimmune diseases, which require ongoing management rather than a cure.
Step-by-step explanation:
The correct answer is b) False, irreversible diseases cannot be completely cured with medication and surgery. Irreversible diseases, such as Crohn's disease, certain autoimmune diseases, and diseases caused by prions, are conditions that, as of now, cannot be completely cured. While medications and surgeries may alleviate symptoms or help manage the disease, they do not constitute a cure. For example, people with Crohn's disease often experience periods of remission where symptoms may be managed, but the disease itself remains. Autoimmune diseases may also be managed with treatment, but the underlying condition persists.
In the case of chronic diseases like type 1 diabetes or cardiovascular diseases, these conditions are lifelong and need ongoing management. Some diseases such as cancer might be cured or managed as chronic conditions with medication. However, it is essential to note that symptom relief or disease management does not equate to a cure. Therefore, while medications and surgeries can be important for improving quality of life and extending life expectancy, they cannot cure irreversible diseases.
