Here's a summary you can use:

"Help me raise funds for my jaw cancer treatment and dental care. Your contribution will go towards medical expenses and supporting me during this challenging time. Every donation counts, and your kindness will make a big difference. Thank you for considering supporting me on this journey."

I am hereby applying to collect financial aid for jaw cancer. I have to take out all the teeth and jaw surgeries.  I've had this problem for 2 years now. I have some small money with me, I'm employed. I have a family, 3 children and a wife and everything comes from my salary. If someone can help, I would be grateful. I'm not looking for it. 

To be damned, I'm asking because I need it, I'm 37 years old, I'm young. 

Or if someone has a dental office to invite me to their place so we can do it. 

I'm from Croatia. Thank you in advance Thank you
