Help....in need of your valued help!!

Im currently on holiday, enjoying the sun in Sydney. I listened to what you said on here and went on our dream holiday. Today ive had a bit of a sore throat and also noticed that the edge of my soft palete on the left hand side has swollen up to the same size as the hatd lump. This is also right next to the hard lump on my hard palate which im worried so muxh about. So now the hard and soft palete on the left hand side are equally swollen.

Is this something that cancer can do in a day?

Literally swell up in a day? Im freaking out as i cant go to the docs here and have to wait another week until i return. The lump had been quite stable since i first noticed it last month but now the soft palete has swollen im scared stiff.
