Should I cancel my whole life policy

My parents bought a whole life insurance policy when I was born and transferred it to me a while back. I have been paying the premiums but I recently read a few posts here about how it may not be worth it. Here is the info I have on the policy, I would appreciate your input. Thank you.

$25,000 whole life policy with Security Benefit Life Insurance with options every 5 years to increase coverage (10k I believe).

Premiums: $8.50/month

Current policy value if I cash out: $850

Reduced paid-up insurance (whatever that means): $13,000

I am 28, married, 1 child, and I have sufficient term life insurance through my employer. I have a pre-existing condition that might make it hard to get life insurance later on, but it shouldn't affect my lifespan.
