Medical careers present the best of all words. They’re generally well-paid, have good demand, show advancement potential, and focus on helping people. The following are the most in-demand jobs by percentage growth that meet those criteria, according to the U.S. Bureau of Labor Statistics (BLS). The increase in employment is projected for 2012 to 2022.

Diagnostic and Medical Sonographers

Diagnostic and medical sonographers operate machines that generate sound waves to image the interior of the human body. Their jobs are expected to increase by 46 percent. Positions require at least an associate degree, which is available at community colleges, or through a four-year program through a college like Adventist University of Health Sciences. You can also obtain an ADU medical sonography degree online.

Home Health Aides

Jobs for home health aides are predicted to increase by 48.5 percent. These workers assist those who are chronically sick, disabled, elderly, or cognitively impaired with daily activities, such as dressing or shopping. They start with a high-school diploma and receive training from their employers. Those working for government-reimbursed agencies require formal training and certification.

Genetic Counselors

Genetic counselors examine their clients’ genetic information to identify risk of specific conditions, such as cancer or cystic fibrosis. Theirs jobs are projected to increase by 41 percent. A master’s degree is the typical minimum education, although some also have Ph.D.’s.

Physical Therapist Assistant or Aide

Physical therapist assistants and aides assist physical therapists who help patients manage pain and regain movement skills. Employment for these professionals is forecast to increase by 41 and 40 percent, respectively. Assistants need an associate degree because they work directly with patients. Aides usually have a high-school diploma and are trained on the job to take care of the facilities and perform clerical tasks.

Physician Assistants

Jobs for physician assistants are predicted to increase by 38.4 percent. These professionals diagnose illness and injuries and prescribe medical treatment while under the supervision of doctors and surgeons. Their positions need at least a master’s degree and at least two-years of postgraduate study. Many applicants for training already have previous healthcare experience as paramedics or registered nurses.

Much of the demand for all these medical jobs is due to the aging baby boomers, which represent about 76 million people or one quarter of the US population, according to the US Census Bureau. As they become older, they’ll seek more medical care, especially since many want to live full and active lives. The healthcare professionals who have these jobs are poised to meet that need.
