Bumps that are cancerous are typically large, hard, painless to the touch and appear spontaneously. The mass will grow in size steadily over the weeks and months. Cancerous lumps that can be felt from the outside of your body can appear in the breast, testicle, or neck, but also in the arms and legs.
A tumor may feel more like a rock than a grape. A cancerous lump is usually hard, not soft or squishy. And it often has angular, irregular, asymmetrical edges, as opposed to being smooth, Dr. Comander says.
Most breast cancers don't cause any pain, even if they first appear as a lump or a bump. But pain can still bring a lump to your attention, when an object hits the side of your breast just so, or you accidentally brush it past something that compresses it.
Lumps or skin thickening on breasts or armpits. Skin changes such as a rash, dimpled skin or skin reddening. Changes to your nipples such as dryness, leaking or inverted nipples.
A Lump A lump or thickening of skin can be an early or late sign of cancer. People with cancers in the breast, lymph nodes, soft tissues, and testicles typically have lumps. (1,2) Skin Changes Yellowing, darkening, or redness of the skin can signal cancer.
They can feel firm or soft. Benign masses are more likely to be painful to the touch, such as with an abscess. Benign tumors also tend to grow more slowly, and many are smaller than 5 cm (2 inches) at their longest point. Sarcomas (cancerous growths) more often are painless.
The best test to determine whether a cyst or tumor is benign or malignant is a biopsy. This procedure involves removing a sample of the affected tissue — or, in some cases, the entire suspicious area — and studying it under a microscope. Karthik Giridhar, M.D.
Scientists have found that for most breast and bowel cancers, the tumours begin to grow around ten years before they're detected. And for prostate cancer, tumours can be many decades old. “They've estimated that one tumour was 40 years old. Sometimes the growth can be really slow,” says Graham.
An infection or abscess is perhaps the most common cause behind a mass that is mistaken for a tumor. In addition, cysts may arise from inflamed joints or tendons as a result of injury or degeneration. Inflammatory conditions, such as rheumatoid arthritis, can also result in soft tissue masses.
See a GP if:
your lump gets bigger. your lump is painful, red or hot. your lump is hard and does not move. your lump lasts more than 2 weeks.
Cancers tend to feel much harder than benign cysts and fibroadenomas. Both benign and malignant masses can be rounded and mobile. Only when cancers are quite advanced are they fixed to skin or the underlying chest wall, and not moveable.
Bumps that are cancerous are typically large, hard, painless to the touch and appear spontaneously. The mass will grow in size steadily over the weeks and months.

A breast lump that's painless, hard, irregularly shaped and different from surrounding breast tissue might be breast cancer. Skin covering the lump may look red, dimpled or pitted like the skin of an orange. Your breast size and shape may change, or you may notice discharge from the nipple.
You may be able to see a growth. Certain things about the image might even suggest that it's likely to be cancerous. But there are many benign (noncancerous) tumors that look very much like cancerous growths. That's why, if your doctor suspects cancer from imaging, they will almost always follow up with a biopsy.
“A cyst is usually a benign condition. But they sometimes need to be drained or removed because they can cause symptoms.” In contrast, tumors are typically more solid collections of tissue. They occur when cells grow uncontrollably when they shouldn't, or when cells don't die when they should.
Tumors and cysts are two types of growth. They can be similar in appearance but have different causes. To determine whether a person has a tumor or a cyst, a doctor may use imaging techniques or take a biopsy.
Benign tumors are not usually problematic. However, they can become large and compress structures nearby, causing pain or other medical complications.
Cyst – a fluid-filled lump under the surface of the skin that moves when you touch it. Skin abscess – a hard, painful lump that may be red and hot to the touch. 'Skin abscesses usually contain pus and are a sign of infection,' says Dr Saloojee.
Fatigue. Lump or area of thickening that can be felt under the skin. Weight changes, including unintended loss or gain. Skin changes, such as yellowing, darkening or redness of the skin, sores that won't heal, or changes to existing moles.
