The symptoms of groin cancer, which is commonly referred to as testicular cancer, include painless swelling or a lump in the testicle, pain in the scrotum or testicle, and dull aching pain in the groin or lower abdomen, according to Cancer.net. Fluid buildup may also be noted in the scrotum.
Other symptoms of possible testicular or groin cancer include a change in the way the testicles feel, such as one testicle suddenly feeling firmer than the other, notes Cancer.net. The scrotum may also begin to feel heavy, and the testicles may become smaller or grow larger. The breasts may also be affected and may grow or become tender. Shortness of breath, low back pain, bloody phlegm or sputum, and chest pain may also be seen in late-stage testicular cancer.
Blood clots that are symptomatic of deep vein thrombosis or DVT, which is a serious condition, can result from testicular cancer, and in turn may cause swelling of one leg or both legs, warns Cancer.net. Shortness of breath from the blood clot can also occur. The development of a blood clot is sometimes the first initial sign of the presence of testicular cancer in young to middle-aged men. Early detection through monthly self-exams that look for changes in the testicles is important to the successful outcome of testicular cancer treatment.
