It's not unusual for lymph nodes to swell. It means they're doing their job and are not necessarily cancerous at all.
I am sure the medical staff will check all this for you. If some cancer cells have travelled at least they should be encapsulated in the lymph glands and therefore much easier to sort out.
I use a Nutribullet which macerates all parts of the fruit etc so no part is wasted or extracted out.
