For some people, radiation may be the only treatment you need. But, most often, you will have radiation therapy and other cancer treatments, such as surgery and chemotherapy. Brachytherapy is used to treat cancers of the head and neck, breast, cervix, prostate, and eye. Liquid forms of internal radiation are most often used to treat thyroid cancer.
Individuals skilled in a foreign language who have a passion for helping others learn might want to consider becoming a bilingual teacher. Teachers in this field need at least a bachelor's degree and must pass a teacher certification exam. Bilingual certification also might be an option. Bilingual teachers typically have two paths available to them: teaching a foreign language to English-speaking students or teaching English to non-native speakers.
The simple answer is YES but there are all sorts of caveats. It depends on where you live and what you teach. The key to success as a tutor is getting referrals. If you are a good teacher you are more likely to get referrals. Some people are naturally good teachers, other become good through experience. If you spend time as a classroom teacher it will definitely help you as a tutor. It's impossible to say how long you need to be a classroom teacher in order to 'learn your trade' but I would say at least 5 years. It is a bit of a sweeping generalization but I would suggest that nobody under 30 years should consider being a full-time tutor if there are other employment options open to them.
