Dear 03clutters, Your mother has Stage 4 cancer and as you are well aware, the prognosis is not good. Although cancers begin insiduously and painlessly, as they advance in stage, there is entrapment of nerve tissues within the cancer which cause this kind of excrutiating pain. At this moment probably there is involvement of the diaphragm which may be causing her pain beneath the breasts. It seems your mother is not on Chemotherapy after the Exploratory laparotomy and Debulking of the cancer. What she needs is what we call as Palliative Care. Every human being is entitled to pain-free living and as dignified a life as possible. Explore in your vicinity if there are Palliative Care Centres or discuss with your doctor use of stronger pain killers like injectible Tramadol or Morphine, Fentanyl patches etc. Its not just pain management, its a whole lot of other issues to improve the quality of life. Nutrition is another important aspect. If your mother is accepting by mouth, try and give her high protein food and supplement with protein powders. Encourage her to move about but if she is unable to, change her sides on the bed every 1-2 hourly so that she does not develop bed sores. The patient may require full time care. In all this run-around don t forget to care for the caretaker - you. Its extremely important for you to also take a nourishing diet, take adequate rest, use your circle of friends to take turns so that you can take a break. Keep your spirits up although its easier said than done. Take pleasure in simple acts of life - sharing a cup of tea with your mother in relaxed silence once a while. AND don t allow any feeling of guilt whenever you are unable or helpless to do more than you are physically capable of. Its ok......... My wishes with you.
