Most bumps, spots, growths, or moles do not need any type of home treatment. However, the following measures may be helpful.

• Keep the area clean and dry. Wash with a mild soap and warm (not hot) water. Do not scrub.
• Avoid irritation.
  • Do not squeeze, scratch, or pick at the spot.
  • Leave the spot exposed to the air whenever possible.
  • Adjust your clothing to avoid rubbing the bump or spot, or cover it with a bandage.
• Conceal a mole or birthmark if you are embarrassed by how it looks. Many cosmetics are designed for this purpose.
• Use a humidifier in your home in the winter or all year if you live in a dry climate.
• Shower after swimming or using a hot tub to rinse off chlorine or salt water. Use a moisturizer after showering.
• Perform a skin self-exam to learn about your skin. This will help you spot new skin growths.
• Eat a balanced diet and drink 8 to 12 glasses of water each day. For more information, see the topic Healthy Eating.

Protect your skin from the sun:

• Limit your exposure to the sun, especially from 10 a.m. to 3 p.m.
• Wear protective clothing, including a wide-brimmed hat, a long-sleeved shirt, and pants.
• Wear sunglasses that block ultraviolet (UV) rays.
• Use a sunscreen that blocks ultraviolet rays (both UVA and UVB) and has a sun protection factor (SPF) of 15 to 30 every day, all year, even when it is cloudy.
• Use a product with an SPF of 15 to 30 on the backs of your hands.
• Do not use tanning booths and sunlamps, which give off ultraviolet radiation and can cause skin damage and increase the risk of skin cancer.

Try the following measures if a bump, spot, or growth shows minor signs of infection, such as a small amount of pus or redness around the bump:

• Gently wash the spot with an antibacterial soap once or twice a day.
• Leave the spot unbandaged, unless it becomes irritated or dirty.
• If a spot becomes dirty or irritated, apply an antibiotic ointment, such as bacitracin or polymyxin B sulfate, and cover it with an adhesive bandage. The ointment will keep the spot from sticking to the bandage.

  Note: Stop using the ointment if the skin under the bandage begins to itch or develops a rash. The ointment may be causing a skin reaction.

• Change the bandage every day and any time it gets wet. If a dressing is stuck to a scab, soak the dressing in warm water to soften the scab and make it easier to remove the bandage.
• Watch for other signs of infection, such as increasing pain, swelling, redness, heat, fever, or chills.
