Sell before biopsy? WTF are you thinking? Looking at those tumor pics, we all know the biopsy is going to be golden. Patience. Oh and the chart looks like clockwork: moving down until sometime next week, then...
Don't oversimplify it, the tumor is gradually dying due to apoptosis moving from the core outwards, and with each shower more parts are completely dead and detach from the cancer tissue that is still alive.
They don't make a claim anywhere that the tumors just magically fall off in one go...
