What type of treatment is characterized as being non-surgical and less invasive?

The correct answer is characterized as non-surgical and less invasive treatments that aim to manage a condition while preserving as much of the normal function and appearance as possible. Conservative treatment typically includes options such as radiation therapy, hormonal therapy, or chemotherapy, which focus on minimizing long-term effects and avoiding major surgical interventions.

This approach is often favored for patients who may not be ready for surgery or who have other health considerations that make invasive procedures riskier. The emphasis on preserving quality of life, avoiding complications associated with surgery, and providing effective care makes this approach an essential part of treatment options.

Other types of treatments, such as radical or aggressive treatments, generally involve more extensive procedures or therapies that may have higher risks and potential complications associated with them. Invasive therapy typically indicates procedures that require surgical intervention, which goes against the principle of non-invasiveness that defines conservative treatment.
