The yellow scab in the middle of the hamster's belly is the hamster's scent gland, which is usually only found in male hamsters. Scent glands emit scent to attract female hamsters when they are in heat. The scent glands will form solid lumps over time. If they are blocked, you can use a cotton swab dipped in water to remove them.
