Orthotists and Prosthetists are professionals who provide aid to patients with disabilities. They fix them to artificial limbs (prosthetics) and help them to regain stability. There are times when people lose their limbs in an accident. In some other occasions, they are born without a limb or orthopaedic impairment. Orthotists and prosthetists play a crucial role in their lives with fixing them to assistive devices and provide mobility.

A pathologist diagnoses diseases by examining body fluids, tissues, and organs. They perform tests, microscopic analysis, and autopsies to identify abnormalities and causes of illness. Working mainly in hospitals and labs, they collaborate with doctors to guide treatment. The field offers growing career opportunities in clinical practice, research, and education due to rising demand for diagnostic services.

A Veterinary Doctor diagnoses, treats, and prevents diseases in animals. They perform surgeries, advise on nutrition, and guide animal care and breeding. To become one in India, students must complete a Bachelor’s in Veterinary Science (B.V.Sc) after studying Physics, Chemistry, and Biology in Class 12. The role combines medical expertise with compassion for animal welfare.

A Speech Therapist (Speech-Language Pathologist) diagnoses and treats speech, language, communication, and swallowing disorders across all ages. They work in hospitals, schools, clinics, and more.

The audiologist career involves audiology professionals who are responsible to treat hearing loss and proactively preventing the relevant damage. Individuals who opt for a career as an audiologist use various testing strategies with the aim to determine if someone has a normal sensitivity to sounds or not. After the identification of hearing loss, a hearing doctor is required to determine which sections of the hearing are affected, to what extent they are affected, and where the wound causing the hearing loss is found. As soon as the hearing loss is identified, the patients are provided with recommendations for interventions and rehabilitation such as hearing aids, cochlear implants, and appropriate medical referrals. While audiology is a branch of science that studies and researches hearing, balance, and related disorders.

An oncologist is a medical doctor who diagnoses and treats cancer using chemotherapy, radiation, surgery, and other therapies.
