Joyce, I am not a big fan of sodium bicarbonate and maple syrup to begin with. Other than cancers that occur from the mouth through the digestive tract and on to the anus, there is really no way for the sodium bicarbonate to reach the site of the cancer. It might help lower pH a bit, but the way human digestion works there is simply no way for a mixture of maple syrup and baking soda to make it through the digestion system into the blood stream and to tumors such as those found in the uterus and cervix. To think otherwise is pretty much in the category of uban myth. It is my further opinion that the biggest proponent for sodium bicarbonate against cancers, Dr. Tulio Simoncini, is pretty much a fraud and charlatan.
As one astute observer opined, baking soda will also remove corrosion on battery terminals - but it won't get there to do the job if you put it in your gas tank.
If it appears to be working for you for whatever reason, that is fine. I would submit that the anti-cancer protocol I suggest would work far better - and nowhere in it will you find a recommendation for sodium bicarbonate or maple syrup.
