Cancerous lumps are hard and painless. They might seem to appear overnight and grow with time. A cancerous lump may block your windpipe or create pressure in the throat or nose. See your provider immediately if you notice these kinds of symptoms.
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.
With most breast cancers, each division takes one to two months, so by the time you can feel a cancerous lump, the cancer has been in your body for two to five years.
Most lumps and swellings are benign (not cancerous) and are harmless, especially the kind that feel soft and roll easily under the fingers (such as lipomas and cysts). A lump or swelling that appears suddenly (over 24 to 48 hours) and is painful is usually caused by an injury or an infection.
However, the only way to confirm whether a cyst or tumor is cancerous is to have it biopsied by your doctor. This involves surgically removing some or all of the lump. They'll look at the tissue from the cyst or tumor under a microscope to check for cancer cells.
It is impossible to tell if a lump is cancerous or benign from self-examination alone. Other symptoms a person should look out for include nipple discharge, breast skin dimpling that resembles orange peel, and changes in nipple and breast color.

Here's the take-home point: a 1 millimeter cluster of cancerous cells typically contains somewhere in the ball park of a million cells, and on average, takes about six years to get to this size. Generally, a tumor can't be detected until it reaches the 1 millimeter mark.
See a GP if:
your lump is painful, red or hot. your lump is hard and does not move. your lump lasts more than 2 weeks. a lump grows back after it's been removed.
First, don't panic — 80 to 85 percent of breast lumps are benign, meaning they are noncancerous, especially in women younger than 40.
Sometimes, a cancer diagnosis comes out of the blue, with no symptoms at all. But more often, there are various symptoms that may be warning signs of the disease.
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.
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.
A lump that feels firm and doesn't easily move under the skin is more likely to be cancerous than a soft, moveable lump. But moveable lumps can be suspicious, too. If you're at high risk for cancer, your doctor may recommend a biopsy for a lump without a known cause.
The smallest lesion that can be felt by hand is typically 1.5 to 2 centimeters (about 1/2 to 3/4 inch) in diameter. Sometimes tumors that are 5 centimeters (about 2 inches) — or even larger — can be found in the breast.
Malignant tumors can grow quickly and spread to other parts of the body in a process called metastasis. However, not all malignant tumors grow quickly; some can grow much slower over time. The cancer cells that move to other parts of the body are the same as the original ones, but they can invade other organs.
Cancers of exactly 2 cm in size occupy a special niche in breast oncology. That size is the one at which breast cancer is most commonly diagnosed (the “modal size”) and 2.0 cm marks the boundary between stage i and ii for node-negative breast cancers and between stage ii and iii for node-positive breast cancers.
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.
A doctor may use an ultrasound to examine a cyst or tumor located deep within the body. Ultrasound imaging can often show whether a lump is hollow, fluid-filled, or a collection of cells. In some cases, a doctor may request a biopsy, which involves removing the lump or cells from it.
The most common warning sign of skin cancer is a change on the skin, especially a new growth or a sore that doesn't heal. The cancer may start as a small, smooth, shiny, pale or waxy lump. It also may appear as a firm red lump. Sometimes, the lump bleeds or develops a crust.
Physicians should disclose a cancer diagnosis in a personal setting, discussing the diagnosis and treatment options for a substantial period of time whenever possible.
In women, breast cancer lumps are usually found in the upper outer quadrant of the breast. In men, they're usually found near the nipple. Regardless of gender, breast cancer can start anywhere there's breast tissue, from the breastbone to the armpit to the collarbone.
