Last week, I completed my note about Cerebellopontine Angle (CPA) Tumor where I read a fascinating treatment option: observation. Since 85% of CPA tumors are benign, observation became an option. Doing nothing but watch it slowly grows. From a palliative perspective, this makes sense. In fact, it relates to what Atul Gawande observed about what does it mean to be either Dr. Informative or Dr. Knows-Best (Paternalistic model).
