Hello @osu-bd!
One of the biggest issues I've noticed that effects people at a more personal level is the financial burden a specific diagnoses can incur upon someone. There are people who will hide a diagnosis if they decide to not forgo treatment due to how costly it would be. Hospital bills for cancer and other potentially treatable diseases can rack up quickly, and without a lot of outside help or resorting to making money through illegitimate (in the eyes of the law) means, many people can't afford them.
