Rita Wilson took to her Twitter account on Wednesday to thank her supporters, one day after revealing she has breast cancer and undergone double mastectomy and reconstructive surgery. The 58-year-old actress - who is married to actor Tom Hanks - tweeted: 'I am overwhelmed with gratitude by your prayers and good wishes and the kindness you're sending. Thank you. Thank you.' On Tuesday, she shared the news of her disease through a statement published by People magazine. Thanking her supporters: Rita Wilson took to her Twitter account on Tuesday after revealing she has breast cancer and undergone double mastectomy and reconstructive surgery (pictured in September 2014) Rita, who took a leave of absence from Broadway play 'Fish in the Dark' earlier this month, revealed she was recently diagnosed with breast cancer and completed a double mastectomy and reconstructive surgery. She explained that her first test for cancer came back negative but that she was correctly diagnosed after seeking a second opinion and underwent the procedure last week. 'Last week, with my husband by my side, and with the love and support of family and friends, I underwent a bilateral mastectomy and reconstruction for breast cancer after a diagnosis of invasive lobular carcinoma,' she said in the statement. Grateful for the outreach: 'I am overwhelmed with gratitude by your prayers and good wishes and the kindness you're sending. Thank you. Thank you' By her side: The star - married to Tom Hanks - announced on Tuesday that she was recently diagnosed with cancer and has undergone a double mastectomy (pictured together in February) 'I am recovering and most importantly, expected to make a full recovery. Why? Because I caught this early, have excellent doctors and because I got a second opinion.' A mastectomy is an operation that removes all or part of the breast. Before the diagnosis, Wilson said she had 'vigilantly monitored' her health with mammograms and MRIs because she knew she had an underlying condition of LCIS, (lobular carcinoma in situ)'. The mother-of-two explained that she recently underwent a breast biopsy, but no sign of cancer was discovered until she sought the opinion of a second doctor on the advice of a friend. The doctor discovered the cancer and she then sought out the opinion of another pathologist, who confirmed the diagnosis, she said. Recuperation: 'I am recovering and most importantly, expected to make a full recovery' Advice: She shared the news on Facebook and linked to a statement printed by People magazine. Her cancer was not found in the first round of tests so she encourgaed others to seek a second opinion, like she did . Rita, who married Oscar-winner Tom in 1988, went on to implore others to seek a second opinion before thanking her loved ones for their support. 'I share this to educate others that a second opinion is critical to your health,' she said. 'You have nothing to lose if both opinions match up for the good, and everything to gain if something that was missed is found, which does happen. Early diagnosis is key.' On Facebook on Tuesday, she encouraged other women to seek a 'necessary and vital' second opinion if they found themselves in similar situations. Treatment: Wilson, pictured last year, said she underwent two  breast biopsies before she was diagnosed . 'Not just by another doctor but by another pathologist,' she added. 'I'm doing well and getting stronger every day.' Following her announcement, famous friends passed on their best wishes to the actress. 'Sending the wonderful Rita Wilson my love and best wishes for a speedy recovery and good health,' Katie Couric wrote on Twitter on Tuesday morning. Support: Celebrity friends flocked to Twitter to pass their best wishes to the actress after her announcement . Thankful: CNN host Christiane Amanpour noted how Wilson's statement will help future families . Christiana Amanpour added: 'Wishing my good friend @RitaWilson the best as she makes this important announcement, which will help millions of women and their families.' 'Sending all my love to the brave and beautiful @RitaWilson,' Josh Groban tweeted. Wilson released the statement on Tuesday after it was announced earlier this month that she had temporarily left the Broadway play, written by and starring Larry David. At the time, a spokesperson said Wilson was expected to return to the stage on May 5. While on medical leave, she has been replaced by Glenne Headly. Admiration: Singer Josh Groban also sent his best wishes to the actress on Twitter on Tuesday . By her side: Actress Christina Applegate also sent her love to Wilson . Wilson is also known as the mother of Marnie, played by Allison Williams, in HBO's 'Girls'. She has two sons with Hanks, Chester Marlon, 24, and Truman Theodore, 19, as well as two stepchildren from Hanks' previous marriage - actor Colin Hanks, 37, and writer Elizabeth, 32 - to whom Wilson is close. Hanks and their mother, Samantha Lewes, had met in college but divorced in 1987, the year before he married Wilson. Lewes passed away in 2002, when she was just 49, after battling bone cancer. Wilson's message to other women to get screened comes just days after Taylor Swift revealed her mother, Andrea, had been diagnosed with cancer. She also urged her fans to remind their parents to get checked. Family: Wilson is pictured with Hanks and one of their sons, Chester, in December 2011. The couple has two sons together and Hanks is also father to a daughter and son from his first marriage . Invasive lobular carcinoma is a type of breast cancer that starts in the milk-producing glands of the breast and spreads in a web-like manner. Due to this, it does not typically form a lump, as is expected with breast cancer, and instead causes a thickening of the tissue, making one part of the breast feel fuller than other areas. Other symptoms including a change in the texture of appearance of the skin on the breast, such as dimpling, or an inverted nipple. Women with this type of breast cancer are usually a few years older than women diagnosed with other types, and it is more likely to occur in both breasts compared with other types. The cancer is invasive, which means it has the potential to spread to other parts of the body. It can be found through screening tests including physical exams or mammograms. Mammograms are encouraged yearly when a woman turns 40s or earlier if they have a family history of breast cancer. Treatment includes removing part or all of the breast followed by chemotherapy or radiation. According to the American Cancer Society, more than 180,000 women in the U.S. are diagnosed with invasive breast cancer each year, and about one in ten cases are invasive lobular carcinomas. The earlier the diagnosis, the better the prognosis. Patients have a slightly better outlook for both short- and long-term survival compared to other types of breast cancer. According to a study by Breast Cancer Research, the five-year survival rate is 85 per cent.
