After colonoscopy AF noted and large blood clot on the lung. Next day advanced ovarian cancer diagnosed from scan. Now five weeks after big op and back into chemo breathlessness stops me feeling better. On 2.5 Bisoprolol and Digoxin and daily injection of Clexanne. Although a wonderful cancer team feel this breathlessness and the effect on my life not taken seriously. Can someone tell me the connection with cancer if there is one? Will I always have this condition? It makes me an invalid. Worse than the cancer.
