Breast cancer may be elongated or oval in shape when touched, and you cannot determine whether it is breast cancer simply by the shape you touch. Breast cancer is a malignant tumor that belongs to breast surgery, and patients may experience abnormal changes in the breast skin, such as orange peel-like changes, chest pain, nipple discharge, nipple blood spillage, and a lump inside the breast. The lumps are usually irregular in shape, and may be oval or other shapes, or they may form strips. You can’t judge the disease simply by the shape you touch, you need to go to the hospital in time to clarify the nature of the tumor through breast ultrasound, mammogram, and if you suspect malignant tumors, you need to carry out puncture biopsy and take histopathological examination in order to diagnose whether it is breast cancer or not. To sum up, if you suspect that you have breast cancer, you should not judge it by touch, but should consult a doctor in time and do systematic examination to confirm the diagnosis.
